Description

Technical Field

[0001] This invention relates to a rockerpoint adjustment element suitable for placement in a shoe. Specifically, the rockerpoint adjustment element is configured to enable movement and / or alteration of the rockerpoint of the shoe. Background Technology

[0002] In recent years, sports products have undergone substantial improvements aimed at maximizing athlete performance, such as by adjusting the shape, form, and / or materials of the products. These improvements have impacted sports products manufactured for the mass market as well as those specifically designed for individual athletes, such as professional athletes.

[0003] However, in many cases, further optimization—configuration for mass production to meet the needs and requirements of athletes—will require adapting the sports product to individual athletes with their specific needs and requirements. This is due to the fact that every person, and therefore every athlete, is different, for example, having different body proportions, limb lengths, foot sizes, and / or centers of mass.

[0004] Individualized configuration of sports products to meet the specific needs of athletes is particularly important in the field of footwear and / or athletic footwear. This is especially true in endurance sports, where athletes endure prolonged physical stress, such as marathons, where even small improvements to shoes can lead to measurable performance improvements.

[0005] A key parameter affecting athlete performance is the shoe's pivot point. For example, the optimal pivot point position depends on the athlete's individual gait pattern. Therefore, products designed for the mass market cannot take into account the individual pivot point of athletes, and consequently, shoes with individualized pivot points are not available in the mass market. Thus, there is a need for a shoe that allows the pivot point to be adjusted according to the athlete's individual needs, thereby democratizing opportunities and performance outcomes for elite athletes.

[0006] US2006 / 0283046A1 relates to a shoe with a sole including an adjustable stability system, particularly for controlling pronation and / or supination. The stability system includes at least one adjusting member capable of selectively assuming at least two alternative positions—within a corresponding seat present in a component of the sole. The adjusting member has a body having at least two portions or sections having different degrees of compressibility.

[0007] WO 90 / 00866A1 relates to a sole assembly comprising an intermediate sole between an abrasion-resistant sole and a first mounting element. The intermediate sole is composed of foam and exhibits different hardnesses in its heel-forming portion according to the lateral direction. Furthermore, serrated wheels are rotatably mounted in the intermediate sole and protrude to the sides for adjustment. The serrated foam wheels exhibit different hardness zones.

[0008] WO 2008 / 095726 A1 discloses a shoe insert made of an elastic matrix, the upper side of which forms a foot support to accommodate a human foot. Furthermore, an elastically molded part is provided on the lower side of the elastic matrix in the midfoot region, wherein this lower side faces away from the arched shape of the matrix. The elastically molded part disposed below the shoe insole functions as a rolling pad; for example, the molded part has a raised shape on its lower side to support the rolling process.

[0009] US2013 / 0000146 A1 relates to a shoe, particularly a running shoe, having a predetermined plantar line extending from the medial to the lateral plantar point, and a plantar rocker, wherein the plantar rocker is shifted rearward relative to the plantar line toward the heel end by an average plantar rocker spacing.

[0010] US2005 / 060913 A1 relates to an expandable shoe including an outer shell and an adjustable internal assembly disposed within the outer shell. The internal assembly has a controller to adjust the size of the internal assembly, thereby adjusting the corresponding size of the shoe. The internal assembly includes a first sole portion, a second sole portion, and a manually actuated member. The manually actuated member has at least a portion accessible from the outer shell and is engageably and releasably communicated with an engagement member fixed to one of the first and second sole portions. When the actuated member is released from the fixed engagement member, the first and second sole portions can move to adjust the size of the shoe, and when the actuated member engages with the fixed engagement member, the first and second sole portions resist slidable movement relative to each other.

[0011] US 6237255 B1 relates to a device for adjusting a shoe—at least longitudinally—according to the growth of a wearer's foot size. The shoe includes a sole and an upper, wherein the sole has a forefoot and a rearfoot, a lower insole and an upper insole, and the upper includes an instep and a rearfoot portion. The instep is secured to the forefoot portion of the sole, and the rearfoot portion is secured to the rearfoot portion of the sole. The sole includes an extension inserted between the forefoot and the rearfoot, the extension having elements for stopping the length.

[0012] US2009 / 0307929 A1 relates to an adjustable shoe having at least one insole. The adjustable shoe includes a toe section, a heel section, and a midfoot section. The midfoot section has an opening perpendicularly through the layer, such that the midfoot section is elastically flexible to allow variable longitudinal displacement of the relative longitudinal displacement of the toe section and the heel section to alter the length of the layer without significantly altering its width. A retaining mechanism selectively secures the toe section and the heel section in any of a plurality of relative positions. Summary of the Invention

[0013] This application relates to a rocker point adjustment element suitable for placement in a shoe, which addresses at least some of the shortcomings of the prior art described above, and also improves other aspects.

[0014] This invention relates to a rockerpoint adjustment element suitable for arrangement in a shoe. The rockerpoint adjustment element includes at least one segment and means for guiding the at least one segment. Furthermore, the guiding means is configured to guide the at least one segment along a path, such that the at least one segment can move along the path, wherein guiding the at least one segment along the path guides and / or moves the corresponding rockerpoint of the shoe.

[0015] The rocker point adjustment element includes at least one segment and a means for guiding the at least one segment. Guiding the at least one segment may include limiting the mobility of the at least one segment relative to at least one direction. The at least one segment and the guiding means may be connected. Typically, the guiding means is configured to guide the at least one segment along a path, enabling the at least one segment to move along the path. The path may be based on the guiding means and / or the at least one segment. For example, the path may be based on the geometry of the guiding means.

[0016] Furthermore, at least one segment is guided along the path to guide and / or move the corresponding pivot point of the shoe. In other words, as the segment is guided and / or moved along the path, the corresponding pivot point of the shoe is guided and / or moved along the path. Typically, there may be a correlation between the position of at least one segment and the pivot point of the shoe. For example, by moving at least one segment along the path, the pivot point of the shoe can be moved along the path. In particular, moving at least one segment along the path can result in a corresponding movement of the pivot point along the path. In some embodiments, moving at least one segment along the path may not translate into a corresponding movement of the pivot point along the path. For example, the movement of the corresponding pivot point of the shoe may be based on the projection of the path relative to an axis. The pivot point of the shoe may refer to a specific point and / or a specific axis. Furthermore, the pivot point is associated with a region of the shoe, preferably where the region includes the axis associated with the pivot point of the shoe.

[0017] At least one segment is guided along a path, causing the corresponding pivot point of the shoe to be guided and / or moved along that path, allowing for alteration of the shoe's corresponding pivot point. For example, it may allow the corresponding pivot point of the shoe to be changed from a first position to a second position. In particular, the pivot point of the shoe can be adjusted according to the individual athlete's needs and requirements, thereby resulting in measurable performance improvements. Therefore, the pivot point of the shoe can be adapted to the athlete to maximize performance and optimize wearing comfort.

[0018] In some embodiments, a subset of at least one segment may move together as a group. For example, a subset of at least one segment may move as a group between adjacent segments to adjust the rocker point of the shoe. Specifically, the subset of at least one segment may include at least two segments of the rocker point adjusting element. Moving a subset of segments as a group may include moving the segments in the subset by the same amount along a path. In some embodiments, the segments in the subset may be connected to each other, and moving one segment in the subset causes moving of the remaining segments in the subset. The connection between segments may include permanent and / or reversible connections. For example, using a reversible connection may allow reconfiguration and / or exchange of segments within the subset. Typically, the rocker point adjusting element may include: a first subset of segments that moves as a first group to adjust a first rocker point of the shoe; and a second subset of segments that moves as a second group to adjust a second rocker point of the shoe. In particular, the first rocker point may include a rearfoot rocker point, and the second rocker point may include a forefoot rocker point.

[0019] Specifically, the path can be substantially along the longitudinal direction of the shoe. The longitudinal direction of the shoe can be any direction extending from the portion of the shoe adapted to accommodate the rear foot to the portion adapted to accommodate the forefoot. For example, the longitudinal direction of the shoe can be associated with the longitudinal direction of the foot. In particular, the longitudinal direction of the foot can be associated with foot length; for example, the longitudinal direction of the foot can be the direction used to measure the length of the foot.

[0020] The device for guiding at least one segment can be configured to guide at least one segment along the longitudinal direction of the shoe. For example, the shape and / or geometry of the guiding device can be based on the longitudinal direction of the shoe. In particular, the guiding device can extend in the longitudinal direction of the shoe.

[0021] Typically, the guiding device for the rocker point adjustment element can be configured such that moving at least one segment along the path comprises substantially linear motion.

[0022] Moving at least one segment along a path with substantially linear motion may include: the motion being substantially along one direction. Motion substantially along one direction may include a direction in which the projection of the motion onto the path comprises at least 50%, preferably at least 70%, and most preferably at least 90% of the motion. Additionally or alternatively, substantially linear motion may include: the trajectory of motion having bounded curvature. For example, substantially linear motion may at least exclude at least a portion of rotation. Typically, substantially linear motion may be based on translation.

[0023] In some embodiments, moving at least one segment along the path may also include at least partially a torsion of at least one segment. For example, at least one segment may be movable in a substantially linear manner and may be movable in a substantially linear manner in a direction not parallel to the longitudinal direction of the shoe. Mobility in a direction not parallel to the longitudinal direction of the shoe may include: a first portion of at least one segment moving by a first amount in a first direction, and a second portion of at least one segment moving by a second amount in a second direction. Specifically, the first direction may be substantially opposite to the second direction. For example, the first and / or second portions of at least one segment may be associated with the proximal and / or lateral portions of at least one segment. Moving the first portion of at least one segment by a first amount in the first direction and moving the second portion of at least one segment by a second amount in the second direction may cause a torsion of the at least one segment. Causing a torsion of at least one segment may change the pivot point of the shoe from a first position to a second position.

[0024] In some embodiments, at least one segment may move along a path with substantially linear motion, wherein the path is substantially along the longitudinal direction of the shoe. For example, at least one segment may move with substantially linear motion from a first position to a second position along the longitudinal direction of the shoe.

[0025] Moving at least one segment along the path in a substantially linear motion, preferably along the longitudinal direction of the shoe, allows the corresponding pivot point of the shoe to move along the path in a substantially linear motion. This results in a measurable and / or significant change in the pivot point of the shoe, thereby producing measurable performance benefits for the athlete.

[0026] Specifically, at least one segment may comprise block foam and / or granular foam. Additionally or alternatively, at least one segment may comprise polymer-based materials, such as polyamide and / or polyurethane and / or copolyester, and / or rubber blends and / or ethylene-vinyl acetate.

[0027] Furthermore, at least one segment may be separated from adjacent segments by a gap. For example, at least one segment may be separate, such that the guiding means is configured to guide the at least one segment between adjacent segments.

[0028] Separating at least one segment from adjacent segments by a gap may include: the distance between adjacent segments being greater than the extension and / or elongation and / or width of the at least one segment. The size of the gap may be based on the difference between the distance between adjacent segments and the extension and / or elongation of the at least one segment. Typically, a gap may refer to a portion of a rocker point adjusting element that does not include at least one segment. In particular, a gap may refer to a portion of a rocker point adjusting element that does not include a portion of at least one segment. For example, a gap may include at least a portion of a guiding device. In particular, a gap may include at least a portion of a plate / frame / reinforcing element and / or at least a portion of at least one rod.

[0029] Typically, the movement of at least one segment along a path can be based on the degree of separation between that at least one segment and its adjacent segments. For example, the size of the gap can at least partially constrain and / or limit the movement of at least one segment.

[0030] At least one segment may be separable, such that the guiding means is configured to guide the at least one segment between adjacent segments. For example, the guiding means may be configured to guide at least one segment from a first position near a first adjacent element to a second position near a second adjacent element. Guiding at least one segment may be constrained and / or limited based on adjacent segments. For example, at least one segment may be guided from the first position to the second position along the longitudinal axis of the shoe in a substantially linear motion.

[0031] Separating at least one segment from adjacent segments by using gaps allows for movement of that at least one segment between adjacent segments, thereby enabling the corresponding pivot point to be moved between adjacent segments. Therefore, the corresponding pivot point can be adapted to the needs and requirements of an individual athlete, and thus produces measurable performance results.

[0032] Typically, at least one segment can be a block extending from the mesial side of the shoe to the lateral side of the shoe. Specifically, the block can be a continuous block extending from the mesial side of the shoe to the lateral side of the shoe. For example, the block can include a substantially rectangular block. A substantially rectangular block can include a rectangular block where the edges can include curvature. Using a block extending from the mesial side of the shoe to the lateral side of the shoe as a segment allows for precise and easy adjustment of the shoe's pivot point. For example, if at least two blocks are used, the blocks and / or segments can be spaced apart in the longitudinal direction.

[0033] In some embodiments, the pivot point adjustment element may include at least one segment that is separate from other segments in both the longitudinal and transverse directions. Specifically, the pivot point adjustment element may include at least one segment that does not extend continuously from the mesial side of the shoe to the lateral side of the body. For example, gaps may exist between segments relative to the direction from the mesial side of the shoe to the lateral side of the body. In other words, the segment may not be a continuous block extending from the mesial side of the shoe to the lateral side of the body, but rather the segment may be decomposed into at least two sub-segments, wherein these sub-segments are separated relative to the transverse direction. For example, the pivot point adjustment element may include: a first segment movable along a first path, and a second segment movable along a second path; wherein the first segment and the second segment are spaced apart in both the longitudinal and transverse directions. In some embodiments, there may be a first segment associated with the lateral side of the shoe and a second segment associated with the mesial side of the shoe. Typically, the first segment and the second segment are movable independently.

[0034] Typically, the edge of at least one segment may include a bevel and / or may be rounded.

[0035] At least one edge of at least one segment may include a bevel and / or may be rounded. In particular, when at least one segment comprises a rectangular cuboid shape, at least a portion of the twelve sides may include a bevel and / or may be rounded. For example, when at least one segment comprises blocky foam and / or granular foam, at least one edge of the at least one segment may include a bevel and / or be rounded.

[0036] Providing at least a portion of the edges of at least one segment with bevels and / or rounding them prevents the at least one segment from including sharp edges. In particular, it prevents segments containing blocky foam and / or granular foam (e.g., ethylene-vinyl acetate) from having sharp edges. Specifically, when at least one segment is injection molded and / or 3D printed, sharp edges can damage adjacent segments, thereby reducing the lifespan of shoes including rocker point adjustment elements. In some embodiments, if at least one segment is injection molded and / or 3D printed, the edges of at least one segment are beveled and / or rounded. Sharp edges can typically injure athletes when they hold and / or wear the shoe. Furthermore, beveled and / or rounded edges facilitate a smoother transition between segments and gaps when the shoe contacts the ground. For example, beveled and / or rounded edges reduce and / or eliminate creaking and / or rolling sounds from segments when the shoe is in use. Therefore, beveled and / or rounded edges can contribute to athlete comfort.

[0037] The guiding device may be an internal reinforcing element, such as at least one rod and / or plate. In particular, at least one rod and / or plate may be rigid.

[0038] Internal reinforcement elements can be components suitable for improving the stability and / or physical properties of the shoe. For example, internal reinforcement elements may be at least partially included in the midsole of the shoe. Additionally or alternatively, internal reinforcement elements may be at least a portion of a rocker point adjustment element.

[0039] The internal reinforcement element can be at least a rod and / or a plate. For example, a rod can be an element that extends substantially in one direction and / or along a path. A plate can be an element that extends substantially in two directions and / or is substantially described as a surface. In particular, the surface may include curvature; for example, the surface may not be planar. The internal reinforcement element may include multiple rods. For example, multiple rods may be arranged to uniformly cover the shoe. Uniformly covering the shoe may include: the distance between the multiple rods being substantially equal. In some embodiments, the internal reinforcement may include a plate. For example, the plate may substantially conform to the form and / or shape of the shoe, preferably conforming to the form and / or shape of the shoe's midsole.

[0040] Specifically, the rods and / or plates can be rigid. In some embodiments, being rigid may include: the rods and / or plates being more rigid than at least one segment. In particular, the rods and / or plates may be more rigid than at least one segment comprising blocky foam and / or granular foam. Additionally or alternatively, being rigid may include: at least one segment being more rigid than the rods and / or plates. In some embodiments, the stiffness of the rods may vary. For example, a first rod may include a first stiffness, and a second rod may include a second stiffness. Additionally or alternatively, the stiffness of the rods may be the same. Similarly, the stiffness of the plates may include spatial dependence. For example, a first region of the plate may include a first stiffness, and a second region of the plate may include a second stiffness. In particular, the stiffness of the plate on the body side may differ from the stiffness of the plate on the proximal side.

[0041] Typically, the stiffness of a bar and / or plate can include bending stiffness and / or tensile stiffness. For example, stiffness can include bending stiffness. In particular, the bending stiffness of the bar and / or plate can be configured to provide the necessary bending stiffness during running. In some embodiments, the bending stiffness of the bar and / or plate may be lower than the tensile stiffness of the bar and / or plate.

[0042] Using rigid internal reinforcing elements as guiding devices, such as rods and / or plates, allows for the guidance and / or movement of at least one segment along a path, thereby moving the corresponding pivot point of the shoe along that path. Thus, the corresponding pivot point can be adapted to the needs and requirements of an individual athlete, and therefore produces measurable performance results.

[0043] Typically, the guiding device may include a position indicator. The position indicator may include any visible indication on the guiding device from which the position of at least one segment—relative to the guiding device and / or relative to adjacent segments and / or relative to the rocker point adjustment element—can be inferred. Specifically, the position indicator may allow the inference of the distance between at least one element and adjacent elements. Additionally or alternatively, if at least one segment includes first and second segments, then the position indicator may indicate the distance between the first and second segments. For example, the position indicator may include markings and / or ring marks on the guiding device. In particular, rods and / or plates may include markings and / or ring marks. For example, if the rocker point adjustment element includes rods, at least one of the outermost rods, such as the rod furthest to the body and / or the rod closest to the center, may include a position indicator. In some embodiments, all rods may include position indicators. The position indicator on the guiding device helps the user of the rocker point adjustment element to precisely adjust the at least one segment, thereby precisely adjusting the rocker point of the shoe.

[0044] Specifically, at least a portion of the internal reinforcing element may extend through at least one segment. In particular, at least a portion of the internal reinforcing element may extend through at least one segment such that the path corresponds to the extension path of the internal reinforcing element.

[0045] At least a portion of the internal reinforcing element extending through at least one segment may include: at least a portion of the internal reinforcing element being at least partially surrounded by the at least one segment. For example, the at least one segment may include at least one hole through which the internal reinforcing element extends. In particular, if the internal reinforcing element comprises a rod, the at least one segment may include at least one hole, preferably based on the shape and / or cross-section of the rod, through which the rod extends. The number of holes may be based on the number of rods. If the internal reinforcing element comprises a plate, at least one foam segment may include a hole, wherein the hole is based on the shape and / or cross-section of the plate.

[0046] An internal reinforcing element may extend through at least one segment, such that the path corresponds to the extension path of the internal reinforcing element. For example, the hole may be configured such that the at least one segment can be guided and / or moved along the path. In particular, the size of the hole may be larger than the cross-sectional size of the rod and / or plate to ensure that at least one segment can be guided and / or moved along the path. Typically, the shape of the rod and / or plate may associate the corresponding extension direction with the extension direction of the shoe. For example, the rod and / or plate may extend in the longitudinal direction of the shoe.

[0047] Typically, at least one segment may be configured such that the lateral projection of at least one segment relative to the longitudinal axis of the shoe comprises substantially continuous segments.

[0048] The lateral projection of at least one segment relative to the longitudinal direction may include a view of the at least one segment and / or the shoe from the lateral and / or mesial side of the body. For example, the lateral projection may include a view of the shoe and / or at least one segment—in a plane including means for guidance. Substantially continuous segments may include smoothly connected segments.

[0049] In particular, essentially continuous segments may not include gaps.

[0050] The lateral projection of at least one segment relative to the longitudinal axis of the shoe includes substantially continuous segments and may include: at least one segment and / or the lateral and / or mesial views of the shoe do not show a gap relative to at least one segment, the gap extending from the mesial side to the lateral side and / or from the lateral side to the mesial side.

[0051] For example, if at least one segment is separated from an adjacent segment by a gap, the at least one segment may be configured such that the gap relative to the at least one segment, extending from the mesial side to the lateral side and / or from the lateral side to the mesial side, is not displayed in the lateral side view and / or mesial side view of the shoe. In particular, the at least one segment and / or adjacent segments may include interlocking geometry. The interlocking geometry may be configured such that the at least one segment can be guided and / or moved between adjacent segments. For example, the at least one segment may include a protrusion on a side adjacent to the adjacent segment. Additionally or alternatively, the adjacent segment may include a hole configured to receive at least a portion of the protrusion. For example, the geometry and / or size of the hole may be based on the geometry and / or size of the protrusion. In some embodiments, the protrusion of the at least one segment may extend at least partially into the hole independently of the position of the at least one segment, thereby ensuring that the lateral projection of the at least one segment relative to the longitudinal axis of the shoe comprises a substantially continuous segment.

[0052] Typically, even if a gap exists between the segment and at least one adjacent segment, the shoe may comprise substantially continuous segments. For example, the gap may still exist, but if the shoe and / or the rocker point adjustment element is viewed from the mesial side, it cannot be seen through to the lateral side of the body. In other words, adjacent segments are separated by gaps, but they interlock, preventing vision through the gaps. For example, interlocking between segments and adjacent segments can be achieved through non-linear gaps, such as curved gaps and / or notches / grooves in the segments. In particular, curved gaps and / or notches and / or grooves in the segments can obstruct the view from the lateral side of the shoe towards the mesial side.

[0053] A substantially continuous segmentation allows the wearer to not perceive and / or feel gaps while wearing the shoe. In particular, a substantially continuous segmentation facilitates smooth transitions between segments, making the wearer feel no abnormal breaks in the sole.

[0054] Typically, at least one segment may be movable backward relative to the path. Additionally or alternatively, at least one segment may be movable forward relative to the path.

[0055] At least one segment may be movable backward relative to the path. "Backward" can refer to the direction—based on the part of the shoe adapted to accommodate the backfoot (or rearfoot). Similarly, "forward" can refer to the direction—based on the part of the shoe adapted to accommodate the forefoot. For example, at least one segment may be movable backward and / or forward along a path that is substantially along the longitudinal direction of the shoe. Additionally or alternatively, at least one segment may be movable backward and / or forward relative to the path, such that moving at least one segment along the path comprises a substantially linear movement.

[0056] At least one segment is movable backward and / or forward relative to the path, allowing the corresponding pivot point of the shoe to be movable backward and / or forward relative to that path. Specifically, the corresponding pivot point can first move forward, preferably forward relative to the longitudinal direction of the shoe, and then move backward. Therefore, the corresponding pivot point can move in both forward and / or backward directions, allowing for correction of misalignment of the pivot point. In particular, since an optimal pivot point can be reached during the iterative process of moving the pivot point forward and / or backward, it allows for precise adjustment of the pivot point. Therefore, the corresponding pivot point can be precisely adapted to the needs and requirements of an individual athlete, thus producing the highest performance results.

[0057] Specifically, at least one segment can be movable along the path by at least 2 mm, preferably at least 5 mm, and most preferably at least 8 mm. Furthermore, at least one segment can be movable along the path by up to 30 mm, preferably up to 20 mm, and most preferably up to 10 mm. Typically, the size of the gap and / or the size of the segment and / or the length of the path can depend on the shoe size. For example, the size of the gap and / or the size of the segment and / or the length of the path can correspond to a shoe size measured in barleycorns.

[0058] At least one segment can be movable along the path by at least 2 mm, preferably at least 5 mm, and most preferably at least 8 mm, allowing at least one segment to move along the path by at least 5 mm, and most preferably at least 8 mm. For example, at least one segment and adjacent segments can be configured such that at least one segment can move along the path by at least 5 mm, and most preferably at least 8 mm. In particular, the gap between at least one segment and adjacent segments can have a size that allows at least one segment to move along the path by at least 2 mm, preferably at least 5 mm, and most preferably at least 8 mm. The ability of at least one segment to move along the path by at least 8 mm allows the corresponding pivot point of the shoe to move by at least 8 mm. This ensures that the corresponding pivot point of the shoe can change by a sufficient amount so that the athlete's individual needs and requirements can be taken into account. In other words, the ability of at least one segment to move along the path by at least 8 mm ensures sufficient flexibility of the corresponding pivot point of the shoe.

[0059] Furthermore, at least one segment can be movable by a maximum of 20 mm along the path. For example, at least one segment and adjacent segments can be configured such that the movement of at least one segment is restricted to a maximum of 20 mm. Restricting the movement of at least one segment to a maximum of 20 mm can limit the size and / or shape of the gap between at least one segment and adjacent segments. Therefore, sufficient stability of the shoe can be ensured while ensuring sufficient flexibility of the corresponding pivot point of the shoe. In particular, a smooth running experience for the athlete can be guaranteed.

[0060] At least one segment may be arranged in the part of the shoe adapted to accommodate the forefoot. Additionally or alternatively, at least one segment may be arranged in the part of the shoe adapted to accommodate the rearfoot.

[0061] Arranging at least one segment in the portion of the shoe adapted to receive the forefoot may include: accommodating the at least one segment in a portion of the shoe—associated with at most 50% of the forefoot, preferably at most 45% of the forefoot, and most preferably at most 40% of the forefoot. For example, at least one segment may be configured such that it is movable in the area associated with the forefoot. Arranging at least one segment in the portion of the shoe adapted to receive the forefoot allows movement of the corresponding pivot point of the shoe within the portion of the shoe associated with the forefoot. Additionally or alternatively, at least one segment may be arranged in the portion of the shoe adapted to receive the rearfoot. In some embodiments, at least one segment may be arranged in the portion of the shoe adapted to receive the forefoot, and at least one additional segment may be arranged in the portion of the shoe adapted to receive the rearfoot. For example, moving at least one segment arranged in the forefoot portion and at least one segment arranged in the rearfoot portion may collectively contribute to moving the corresponding pivot point of the shoe.

[0062] Typically, a shoe may include multiple pivot points. For example, a shoe may include a rearfoot pivot point and / or a forefoot pivot point. Therefore, it may be desirable to adjust the rearfoot pivot point and the forefoot pivot point individually. For example, at least one segment in the portion of the shoe adapted to receive the forefoot may be configured to adjust the forefoot pivot point of the shoe. In particular, moving at least one segment in the portion of the shoe adapted to receive the forefoot can move the corresponding forefoot pivot point. Similarly, at least one segment in the portion of the shoe adapted to receive the rearfoot may be configured to adjust the rearfoot pivot point of the shoe. In particular, moving at least one segment in the portion of the shoe adapted to receive the rearfoot can move the corresponding rearfoot pivot point. In some embodiments, the segments in the portion of the shoe adapted to receive the forefoot may be adjustable—independent of the segments in the portion of the shoe adapted to receive the rearfoot. Therefore, the forefoot pivot point of the shoe may be adjusted independently of the rearfoot pivot point of the shoe. By independently adjusting the heel pivot point and forefoot pivot point, the shoe can be customized to the athlete's individual needs, thus contributing to optimal performance.

[0063] Typically, the rocker point adjustment element may further include means for securing at least one segment. The means for securing may be configured to fix at least one segment in a corresponding first position.

[0064] Securing at least one segment using a fixing device may include ensuring that the at least one segment cannot move along a path. For example, at least one segment may be fixed relative to a corresponding first position. The corresponding first position may be a position relative to a guiding device. Fixing at least one segment ensures that the at least one segment remains in the corresponding first position. For example, fixing at least one segment in the first position ensures that the at least one segment remains in the first position during the use of the shoe. Typically, fixing at least one segment may include coupling the at least one segment to a guiding device such that the at least one segment becomes immovable relative to the guiding device. In particular, the fixing device may couple at least one segment to the guiding device.

[0065] Specifically, fixing at least one segment at a corresponding first position secures the corresponding first pivot point of the shoe. For example, this at least one segment may have initially been moved to the corresponding first position to move and / or change the corresponding pivot point of the shoe. After adjusting the corresponding pivot point of the shoe according to the athlete's individual needs and requirements, at least one segment may be fixed at the corresponding first position, thereby securing the corresponding first pivot point of the shoe. Typically, the corresponding first pivot point may be the optimal pivot point for the individual athlete.

[0066] In another embodiment, the securing device can be released, allowing at least one segment to move along the path to a corresponding second position.

[0067] Loosening the securing device allows at least one segment to move along the path, even though that segment was initially secured by the securing device. For example, loosening can include, for instance, disengaging at least one segment from the guiding device by removing the securing device. Moving at least one segment from a first position to a second position allows the corresponding pivot point of the shoe to be moved from the first position to the second position. For example, the first pivot point may already be the optimal pivot point for an individual athlete at a first time, while the second pivot point may be the optimal pivot point for an individual athlete at a second time. Therefore, loosening at least one segment allows the corresponding pivot point of the shoe to be readjusted to the individual athlete's current needs and requirements. This ensures optimal and measurable performance effectiveness.

[0068] The means for securing the shoe may include mechanical fastening mechanisms, such as clamping and / or locking mechanisms. Specifically, the mechanical fastening mechanism may include at least one screw and / or nut and / or bolt. Additionally or alternatively, the mechanical fastening mechanism may include nails and / or rivets and / or pins. Typically, the mechanical fastening mechanism may be configured to provide permanent fixation of the shoe's pivot point. Additionally or alternatively, the mechanical fastening mechanism may be configured to provide reversible fixation of the shoe's pivot point, for example, the mechanical fastening mechanism may be released.

[0069] Using a mechanical fastening mechanism ensures that at least one segment is secured so that it will not be unintentionally loosened during the use of the shoe. Furthermore, the mechanical fastening mechanism allows the fastening device to be released, enabling at least one segment to be moved along a path to a corresponding second position. For example, at least one screw could be a sunken screw.

[0070] In other embodiments, the fixing device may include an adhesive, such as a fast-curing adhesive. Additionally or alternatively, the fixing device may be based on a pin / hole locking system. For example, at least one pin may extend from the guiding device, preferably on the side and / or proximal side of the guiding device. In particular, at least one pin may be movable, and at least one segment may be moved along a path by pressing the at least one pin in a direction pointing toward the center of the device for guiding at least one segment.

[0071] Specifically, the mechanical fastening mechanism may include at least one fastening element adapted to engage between at least one segment and at least one adjacent segment.

[0072] The at least one fixing element can secure the at least one segment by engaging it between the at least one segment and at least one adjacent segment. For example, the at least one segment can be secured by the at least one fixing element, a guiding device, and friction between the at least one segment and the adjacent segment. In particular, the number of fixing elements can be based on the number of segments. For example, one fixing element can be associated with each of the at least one segment. Additionally or alternatively, two fixing elements can be associated with each of the at least one segment. In some embodiments, the number of fixing elements associated with different segments can be different. For example, there can be a first number of fixing elements associated with a first segment and a second number of fixing elements associated with a second segment, wherein the first number and the second number can be different. Typically, the at least one fixing element can contain the same material as the at least one segment and / or adjacent segments. Additionally or alternatively, the number of fixing elements can be based on the number of gaps between segments.

[0073] In particular, the dimensions of at least one fixing element may be configured to secure at least one segment in a first position. For example, the at least one fixing element may include a structure compatible with a guiding device.

[0074] The size of at least one fixing element may be based on the size of at least one segment and the gap between adjacent segments. For example, at least one fixing element may be fixed via two fixing elements such that the total size of the two fixing elements corresponds to the total size of the gap between at least one segment and adjacent segments. Typically, at least one fixing element may be configured to fix at least one segment in a first position. For example, the first position may correspond to a first corresponding pivot point of the shoe, preferably wherein the first corresponding pivot point of the shoe is an optimal pivot point relative to the individual athlete.

[0075] The size and / or shape of at least one fixing element may be adapted to secure at least one segment in a first position. For example, the first fixing element may have a first size, and the second fixing element may have a second size, wherein the sizes of the first and second fixing elements are configured to secure at least one segment in the first position. In particular, the first fixing element may be smaller than the second fixing element, which may allow at least one segment to be secured closer to the rearfoot portion of the shoe. Additionally or alternatively, the position of at least one fixing element may be configured to secure at least one segment in the first position.

[0076] A structure compatible with the guiding device allows at least one retaining element to engage between at least one segment and at least one adjacent segment. The compatible structure may include a structure complementary to the structure of the guiding device. For example, the structure may include at least one hole corresponding to the geometry of the guiding device. Specifically, if the guiding device comprises a rod, at least one retaining element may include a hole configured to receive at least a portion of the rod when engaged between at least one segment and at least one adjacent segment. Additionally or alternatively, at least one retaining element may include teeth and / or at least one comb. For example, teeth and / or at least one comb may be configured such that the rod can pass between the teeth.

[0077] Typically, adjusting the pivot point of a shoe can include: remotely adjusting the pivot point of the shoe. For example, remotely adjusting the pivot point of a shoe can include: at least one segment of a remotely adjusting pivot point adjusting element. Specifically, remotely adjusting the pivot point can include: remotely adjusting the pivot point via a wireless connection and / or an electronic connection. For example, the pivot point adjusting element may be configured to access a wireless network and / or connect to an electronic device. In some embodiments, the pivot point adjusting element may be configured to connect to an electronic device and / or a network via a Bluetooth connection. For example, the electronic device may be a portable electronic device, such as a mobile phone and / or a tablet computer and / or a smartwatch.

[0078] In some embodiments, remotely adjusting the pivot point may involve at least one sensor. The sensor may include a sensor adapted to measure the ground contact time of the shoe and / or the pivot point adjustment element. For example, the pivot point adjustment element may include at least one sensor. Additionally or alternatively, at least one sensor may be configured to detect the position of at least one segment of the shoe's pivot point and / or the pivot point adjustment element. In some embodiments, at least one sensor may be configured to detect the position of each of at least one segment of the shoe. For example, at least one sensor may be configured to detect the position of the forefoot pivot point and / or the rearfoot pivot point of the shoe. In particular, at least one sensor may detect the position of a segment in the part of the shoe adapted to accommodate the forefoot and / or the position of a segment in the part adapted to accommodate the rearfoot.

[0079] Typically, the rocker point adjustment element may further include means for automatically adjusting the rocker point of the shoe. For example, the rocker point adjustment element may include means for automatically adjusting the position of at least one segment of the rocker point adjustment element. In particular, the means for automatic adjustment may include mechanical means for adjusting the rocker point of the shoe. Specifically, the means for automatic adjustment may include a motor, such as an electric motor. For example, the means for automatic adjustment may include a linear motor and / or a rotary motor. In particular, the rotary motor may be adapted to convert rotational motion into linear motion, for example, into linear motion of at least one segment of the rocker point adjustment element. In some embodiments, rotational motion may be converted into linear motion based on a lead screw. Specifically, the lead screw may include a buttress thread and / or a round thread and / or a square thread. Additionally or alternatively, the mechanical means may include a screw. In particular, the mechanical means may include an elongated screw extending through at least one segment. For example, the mechanical means for adjustment, such as a screw and / or an elongated screw, may be configured such that rotating the screw and / or the elongated screw causes movement of at least one segment. In some embodiments, the device for automatic adjustment may be connected to at least one sensor. Typically, the device for automatic adjustment may be adapted to automatically adjust the rocker point during (a) single match.

[0080] Typically, at least one sensor is adapted to detect and / or measure running speed, for example. Specifically, the means for automatically adjusting the pivot point is adapted to adjust the pivot point based on running speed (e.g., running speed detected and / or measured by at least one sensor). For example, the means for adjustment can be configured to move the pivot point further back as running speed increases. In other words, the faster the running speed, the further back the means for automatic adjustment can move the pivot point. Specifically, moving the pivot point further back may include moving at least one segment further back, for example, closer to the area suitable for accommodating the rear foot.

[0081] Additionally or alternatively, at least one sensor may be adapted to detect and / or measure, for example, the duration of the flight phase. Specifically, the flight phase duration may include the duration between impacts between the shoe and / or the athlete's foot, for example, the duration between successive impacts between the shoe and / or the athlete's foot. For example, a device for automatic adjustment may be configured to adjust the pivot point based on the flight phase duration.

[0082] Additionally or alternatively, at least one sensor may be configured to detect and / or measure slope and / or tilt. For example, at least one sensor may be configured to detect and / or measure the slope and / or tilt of the shoe and / or the athlete's foot. Typically, the detection and / or measurement of slope and / or tilt may be based on a goniometer. In particular, at least one sensor, especially a goniometer, may be arranged in the shoe. For example, at least one sensor, especially a goniometer, may be arranged in and / or within the midsole, e.g., within the midsole. Additionally or alternatively, at least one sensor, especially a goniometer, may be arranged at and / or within a dial, e.g., a dial associated with the shoe. For example, the dial may include a quick-lacing device. Specifically, by arranging at least one sensor, especially a goniometer, at and / or within a dial, the midsole of the shoe may remain unaffected, e.g., it may remain unchanged. Furthermore, at least one sensor and / or means for automatic adjustment may include means for processing the acquired data, such as the detected and / or measured slope and / or tilt. Additionally, the shoe may include an energy storage device, such as a battery. For example, the energy storage device may be configured to provide means for processing and / or at least one sensor and / or means for utilizing energy for automatic adjustment.

[0083] Additionally or alternatively, the device for automatic adjustment may be configured to adjust the rocker point based on the detected and / or measured slope and / or inclination. Specifically, adjusting the rocker point based on the detected and / or measured slope and / or inclination may include classifying the detected and / or measured slope and / or inclination. For example, the detected and / or measured slope and / or inclination may be classified as uphill and / or downhill and / or level. In particular, classifying the detected and / or measured slope and / or inclination as uphill and / or downhill and / or level may include: the detected and / or measured slope and / or inclination being higher than and / or lower than a threshold. In particular, the detected and / or measured slope and / or inclination may be higher than and / or lower than a threshold, for example, five consecutive steps (but any number of steps may be suitable). For example, when the detected and / or measured slope and / or inclination S is higher than a first threshold t1, such as S≥t1, the detected and / or measured slope and / or inclination can be classified as uphill. For example, the first threshold t1 can be in the range of 0.5% to 7%, preferably in the range of 1% to 6%, more preferably in the range of 1.5% to 5%, even more preferably in the range of 2% to 4%, and most preferably in the range of 2.5% to 3.5%. Additionally or alternatively, when the detected and / or measured slope and / or inclination S is lower than a second threshold t2, such as S≤t2, the detected and / or measured slope and / or inclination can be classified as downhill. For example, the second threshold t2 can be in the range of -7% to -0.5%, preferably in the range of -6% to -1%, more preferably in the range of -5% to -1.5%, even more preferably in the range of -4% to -2%, and most preferably in the range of -3.5% to -2.5%. Typically, the device for automatic adjustment is adapted to adjust the rocker point based at least in part on this classification.

[0084] Additionally or alternatively, at least one sensor may be adapted to detect and / or measure ground contact time, for example. For instance, the detection and / or measurement of ground contact time may be based on detected and / or measured acceleration; for example, at least one sensor may include an accelerometer. Specifically, based on the detected and / or measured acceleration, the landing and / or take-off associated with the stride can be determined. Typically, the means for automatic adjustment may be adapted to adjust the pivot point, for example, based on the detected and / or measured ground contact time. For example, the pivot point may be adjusted to increase roll. Specifically, increased roll can reduce athlete fatigue. In particular, ground contact time may increase in cases of fatigue during prolonged running. Therefore, adjusting the pivot point based on ground contact time allows for taking athlete fatigue into account, thereby improving athlete performance. Typically, at least one sensor may be arranged in the dial and / or midsole. Additionally or alternatively, at least one sensor may be embedded within the dial and / or midsole. In some embodiments, at least one sensor, such as an accelerometer, may be combined with a goniometer as a single unit.

[0085] Additionally or alternatively, at least one sensor may be adapted to detect and / or measure impact acceleration, such as impact acceleration during initial ground contact. For example, the detection and / or measurement of impact acceleration may be based on the detected and / or measured acceleration; for example, at least one sensor may include an accelerometer. Alternatively, the impact acceleration may be based on the athlete's impact. Typically, the device for autoadjustment may be adapted to adjust the pivot point—for example, based on the detected and / or measured impact acceleration. Specifically, the device for autoadjustment may be configured to adjust the pivot point—for example, when the athlete's impact changes. For example, when the impact shifts from a heel impact to a midfoot impact and / or a forefoot impact, the device for autoadjustment may adjust the pivot point such that it shifts further forward, for example, toward an area suitable for receiving the forefoot.

[0086] Typically, at least one sensor, such as an accelerometer and / or a goniometer and / or a piezoelectric device (e.g., for detecting and / or measuring pressure), may be arranged together in and / or within the shoe. Alternatively, different sensors may be arranged in different locations. In some embodiments, at least one sensor may be arranged in the heel portion of the shoe. For example, at least one sensor may be arranged at and / or within a dial on the shoe, such as a dial located at the rear of the shoe. For example, at least one sensor may be attached to a heel stabilizer.

[0087] Additionally or alternatively, at least one sensor may be arranged in an area of ​​the shoe suitable for facing and / or contacting the instep. For example, this area may be suitable for facing and / or contacting the instep. Specifically, at least one sensor may be arranged at the shoelaces.

[0088] Additionally or alternatively, at least one sensor may be disposed in the midsole of the shoe and / or within the midsole. Alternatively or alternatively, at least one sensor may be embedded within the shoe. For example, at least one sensor may be disposed beneath the insole of the shoe.

[0089] Typically, automatically adjusting the pivot point of a shoe may include means for determining the (optimal) pivot point of the shoe. For example, the means for determining the (optimal) pivot point of the shoe may include a processor and / or a storage medium. For example, determining the (optimal) pivot point of the shoe may be based at least in part on an algorithm. Specifically, the algorithm for determining the (optimal) pivot point of the shoe may be based at least in part on data from at least one sensor. Attached Figure Description

[0111] Below, only some possible embodiments of the present invention are described in detail. It should be understood that these exemplary embodiments can be modified in many ways and can be combined with each other as long as they are compatible, and certain features can be omitted as long as they appear unnecessary.

[0112] Figure 1A possible embodiment of a rocker point adjustment element 100 disposed in a shoe is shown. The shoe includes an upper 101, a sole 102, an upper force distribution layer / element 103a, and a lower force distribution layer / element 103b. Typically, force distribution layers / elements 103a and 103b may be optional elements; for example, in some embodiments, the shoe may not include force distribution layers / elements 103a and 103b. Additionally or alternatively, the shoe may include an upper force distribution layer / element 103a and / or a lower force distribution layer / element 103b. Specifically, the upper force distribution element 103a may be used for the upper 101 of the shoe. Additionally or alternatively, the upper force distribution layer / element 103a may not be connected to a movable portion of the rocker point adjustment element 100, such as segment 110. Using upper force distribution layers / element 103a and / or lower force distribution layers / element 103b can help bridge gaps between foams. Specifically, the wearer of the shoe will not feel and / or recognize the empty space. The pivot point adjustment element 100 includes a segment 110 and a plate 120, wherein the plate 120 is configured to guide the at least one segment 110 along a path. For example, the path may be determined by the shape and / or geometry of the plate 120. Furthermore, the pivot point adjustment element 100 includes two adjacent segments 130a and 130b, separated from segment 110 by gaps 140a and 140b. Specifically, gap 140a separates the first adjacent segment 130a from segment 110, and a second gap 140b separates segment 110 from the second adjacent segment 130b. Additionally, the pivot point adjustment element 100 includes a third adjacent segment 130c, which is separated from the second adjacent segment 130b by gap 140c. In other embodiments, the second adjacent segment 130b and the third adjacent segment 130c may be joint adjacent segments, that is, the segment extends over the gap 140c.

[0113] Plate 120 is an internal reinforcing element and extends completely through segment 110 and the second adjacent segment 130b. Furthermore, plate 120 extends at least partially through the first adjacent segment 130a and the third adjacent segment 130c. Typically, plate 120 may follow a curvature to achieve certain beneficial mechanical properties. In some embodiments, the curvature of plate 120 results in a certain degree of local bending stiffness. For example, the closer the plate is to the ground, the more rigid it may be. In some embodiments, plate 120 may include a curvature that follows the curvature of the upper 101 and / or the sole 102. Additionally or alternatively, the curvature of the plate may follow the curvature of the foot. Plate 120 may be a rigid plate and may be more rigid than segment 110. Typically, the pivot point adjustment element 100 may include multiple segments and / or multiple gaps. For example, the pivot point adjustment element may include at least one, preferably at least two, most preferably at least three segments and / or gaps. The number of segments and the number of gaps may be related. For example, a correspondence may exist between the number of segments and the number of gaps. In some embodiments, a first set of segments and / or gaps may be arranged on a portion of the shoe suitable for accommodating the rear foot, and / or a second set of segments and / or gaps may be arranged in an area suitable for accommodating the forefoot.

[0114] Plate 120 is configured such that segment 110 is movable along a path. Specifically, plate 120 extends through segment 110 to allow segment 110 to move relative to plate 120. This path is determined by the geometry and / or curvature of plate 120. Furthermore, the movement of the plate is limited by a first adjacent segment 130a and a second adjacent segment 130b. Specifically, segment 110 is movable over gaps 140a and / or 140b until segment 110a reaches adjacent segments 130a and / or 130b. In some embodiments, segment 110 may not be movable until segment 110 reaches adjacent segments 130a and / or 130b. For example, segment 110 may not be fully movable over gaps 140a, 140b, but only movable over a portion of gaps 140a, 140b.

[0115] Segment 110 is movable relative to plate 120 by an amount of 10 mm in both the rearward and forward directions. In other embodiments, this amount may differ for the forward and rearward directions. For example, the movement in the forward direction may be greater than the movement in the rearward direction. The movable segment 110 moves the corresponding pivot point of the shoe.

[0116] Segment 110 contains foam. Additionally or alternatively, segment 110 may contain non-foam materials. For example, segment 110 may contain block foam and / or granular foam. Similarly, adjacent segments 130a, 130b, and 130c may contain foam. For example, segment 110 and adjacent segments 130a, 130b, and 130c may contain the same material. In other embodiments, the material of adjacent segments 130a, 130b, and 130c may differ from the material of segment 110. Segment 110 has a block shape and extends from the medialside (also called the inner side) of the shoe to the lateral side (also called the outer side). Similarly, adjacent segment 130b has a block shape and extends from the medialside of the shoe to the lateral side. Adjacent segments 130a and 130c extend from the mid-side of the shoe to the side of the shoe body, and their respective geometry follows the geometry of the shoe; that is, adjacent segment 130a has a rounded front portion, and adjacent segment 130 has a rounded rear portion. The edges of segment 110 are rounded, and the edges of adjacent segments 130a, 130b, and 130c are also rounded. In other embodiments, the edges of segment 110 and / or adjacent segments 130a, 130b, and 130c may include bevels. For example, these segments may include bevels to soften these hard edges and provide a smoother transition from the segment to the gap when the shoe is in use, and vice versa. Segment 110 is arranged in the portion of the shoe adapted to accommodate the forefoot. In particular, independent of the position of the movable segment 110, segment 110 is located in the area adapted to accommodate the forefoot. Arranging segment 110 in the part of the shoe suitable for receiving the forefoot allows for adjustment of the shoe's forefoot pivot point.

[0117] Additionally or alternatively, the segment may be located in the portion of the shoe adapted to receive the rearfoot. Arranging this segment in the portion of the shoe adapted to receive the rearfoot allows adjustment of the shoe's rearfoot pivot point. In some embodiments, the pivot point adjustment element may include segments—in the portion of the shoe adapted to receive the forefoot and in the portion adapted to receive the rearfoot. For example, the segments in the forefoot portion and the segments in the rearfoot portion may be independently adjustable. Therefore, the rearfoot pivot point and the forefoot pivot point of the shoe can be adjusted independently.

[0118] Figure 2A possible embodiment of a pivot point adjustment element 200 disposed in a shoe is shown. The pivot point adjustment element 200 includes a segment 210 and five rods 220a, 220b, 220c, 220d, and 220e configured to guide the segment 210 along a path 260. The pivot point adjustment element 200 also includes adjacent segments 230a and 230b, wherein a first adjacent segment 230 is separated from segment 210 by a gap 240a, and a second adjacent segment 230b is separated from segment 210 by a gap 240b. The path 260 is based on the geometry and / or extension of rods 220a, 220b, 220c, 220d, and 220e. For example, the path 260 may substantially follow the extension of rods 220a, 220b, 220c, 220d, and 220e. In particular, the extensions of rods 220a, 220b, 220c, 220d, and 220e are substantially along the longitudinal direction of the shoe.

[0119] Rods 220a, 220b, 220c, 220d, and 220e are configured to guide segment 210 along path 260, allowing segment 210 to move along path 260. Specifically, moving segment 210 along path 260 causes the corresponding pivot point of the shoe to move along path 260. Since rods 220a, 220b, 220c, 220d, and 220e are substantially straight, segment 210 can move along path 260 with substantially linear motion.

[0120] The movement of segment 210 is limited by adjacent segments 230a and 230b. For example, segment 210 may be movable over gaps 240a and 240b until segment 210 reaches adjacent segments 230a and 230b. The distance between the first adjacent segment 230a and the second adjacent segment 230b is greater than the size and / or width of segment 210. In particular, the size of gaps 240a and 240b may be based on the difference between the distance between the first adjacent segment 230a and the second adjacent segment 230b and the size and / or width of segment 210. Regarding the rocker point adjustment element 200, the lateral projection of segment 210 and adjacent segments 230a and 230b along the longitudinal axis of the shoe does not include substantially continuous segments. In practice, in embodiment 200, the lateral projection will include the gaps, i.e., gaps 240a and 240b. More precisely, the lateral projection will include gaps—having substantially the same dimensions and / or width and / or geometry as gaps 240a, 240b. Segment 210 comprises a block shape and extends from the mid-side of the shoe to the side of the shoe. Segment 210 contains foam, such as block foam and / or granular foam. Similarly, adjacent segments 230a, 230b may contain foam. In particular, the material of segment 210 may be the same as the material of adjacent segments 230a, 230b.

[0121] Rods 220a, 220b, 220c, 220d, and 220e are internal reinforcing elements. Rods 220a, 220b, 220c, 220d, and 220e extend through segment 210. Specifically, rods 220a, 220b, 220c, 220d, and 220e extend through segment 210 in a manner that allows segment 210 to move. Rods 220a, 220b, 220c, 220d, and 220e may further extend through adjacent segments 230a and 230b. Typically, the segments may be movably fixed to reinforcing elements, such as rods and / or plates, such that the segments can slide on a structure passing through the body of the segment. For example, segment 210 may be movably fixed to rods 220a, 220b, 220c, 220d, 220e, such that segment 210 can slide on at least a portion of rods 220a, 220b, 220c, 220d, 220e. In particular, segment 210 may slide between adjacent segments 230a and 230b.

[0122] The pivot point adjustment element 200 also includes two screws 250a and 250b for securing segment 210 in a respective first position. Specifically, the screws extend at least partially through segment 210. In embodiment 200, the first screw 250a couples segment 210 to rod 220b, and the second screw 250b couples segment 210 to rod 220d. In other embodiments, different numbers of screws may be used, and different screws may couple segment 210 to different rods. For a more detailed explanation of the securing mechanism, refer to... Figure 5 .

[0123] Figure 3 An embodiment of a rocker point adjustment element 300 including overlapping geometry is shown. The rocker point adjustment element 300 includes segments 310, guiding means (not shown), and adjacent segments 320a, 320b. The guiding means is configured to guide at least one segment along a path 340. For example, the guiding means may be a plate 120 and / or rods 220a, 220b, 220c, 220d, 220e. In other embodiments, the guiding means may be implemented in different ways. Segments 310 include protrusions 315a, 315b located on opposite sides of segments 310. Furthermore, a first adjacent segment 320a includes a recess 325a adapted to receive at least a portion of the protrusion 315a. Furthermore, a second adjacent segment 320b includes a recess 325b adapted to receive at least a portion of the protrusion 315b. For example, protrusions 315a, 315b and recesses 325a, 325b may be configured such that, independent of the position of segment 310 on path 340, at least a portion of protrusion 315a extends into recess 315a, and / or, at least a portion of protrusion 315b extends into recess 325b.

[0124] Regarding embodiment 300, the lateral projection of segment 310 and adjacent segments 320a, 320b relative to the longitudinal axis of the shoe comprises substantially continuous segments. Specifically, the lateral projection will not fully encompass gaps 330a, 330b, because gaps 330a, 330b do not extend linearly from the mid-side of the shoe to the lateral side. More precisely, the gaps extend from the lateral side of the shoe to the mid-side via a curved path, wherein path 340 is based on the shape and / or geometry of protrusions 315a, 315b and / or recesses 325a, 325b.

[0125] Typically, the protrusions 315a and 315b may have different geometries and / or different dimensions. In some embodiments, the overlapping geometry is implemented only relative to one side of segment 310. For example, segment 310 may include only one of the protrusions 315a or 315b, and / or only the first adjacent segments 320a or 320b may include corresponding recesses 325a and 325b. In particular, only the first adjacent segment 320a may include a recess 320a, and segment 310 may include only the protrusion 315a. Furthermore, the second protrusion 315b may be absent, and segment 310 may have a flat side facing the adjacent segment 320b. Similarly, the second adjacent segment 320b may not include a recess 325b and may have a flat side facing segment 310.

[0126] Figure 4A and 4B An embodiment of a rocker point adjustment element 400 disposed in a shoe is shown. For example... Figure 4A As shown, the rocker point adjustment element 400 includes segments 410 and rods 420a, 420b, 420c, 420d, and 420e, which are configured to guide at least one segment along a path. The rocker point adjustment element 400 further includes adjacent segments 430a and 430b separated from the segments 410 by gaps 440a and 440b.

[0127] Figure 4B The image shows a cross-section of the shoe and / or rocker point adjustment element relative to a plane defined by points A and B (shown by a dashed line passing through points A and B). For example, this plane may be perpendicular to the direction of extension of the shoe. Specifically, this plane may be perpendicular to the direction of extension of reinforcing elements (e.g., rods and / or plates). Segment 410 may include holes corresponding to the dimensions of rods 420a, 420b, 420c, 420d, 420e. Specifically, the holes allow rods 420a, 420b, 420c, 420d, 420e to extend through them. Specifically, the holes allow segment 410 to be guided along a path by rods 420a, 420b, 420c, 420d, 420e.

[0128] Furthermore, the pivot point adjustment element 400 includes screws 450a and 450b. In other embodiments, the pivot point adjustment element 400 may include only one screw or at least three screws. Screws 450a and 450b are configured to secure segment 410 in a respective first position. For example, segment 410 may include threads 460a and 460b configured to receive the respective screws 450a and 450b. In particular, threads 460a and 460b may extend from the proximal and / or lateral side of segment 410 toward the shoe and / or the center of segment 410. Typically, the number of screws and / or threads may vary. For example, the number of threads on the first side of segment 410 may differ from the number of threads on the second side of segment 410.

[0129] When screws 450a and 450b are screwed into their respective threads 460a and 460b, the screws and threads secure segment 410 in its respective first position. For example, segment 410 may be secured in the first position, creating gaps 440a and 440b. In particular, the segment may be secured in the first position such that the shoe's pivot point is fixed in its respective first position. The first position of the pivot point may correspond to the shoe's—relative to the individual athlete's—optimal pivot point.

[0130] Figure 5 A specific embodiment of the device 500 for securing is shown. Compared to the configuration in embodiment 400, the screw enters the segment 510 from the underside, preferably where the underside of segment 510 corresponds to the underside of the shoe. Segment 510 includes at least one thread 540 into which the screw 530 can be screwed. Typically, the device 520 for guiding may include a plate and / or a rod. For example, the device for guiding may include at least one of plate 120 and / or rods 220a, 220b, 220c, 220d, 220e. For example, the device for guiding may be an internal reinforcing element and may extend through segment 510.

[0131] For example, if screw 530 is screwed into thread 540, the screw can contact the guiding device 520. By contacting the guiding device 520, screw 530 can hold segment 510 in a corresponding first position. For example, contacting the guiding device can include establishing friction between screw 530 and the guiding device 520, such that segment 510 is held in the corresponding first position. Typically, the screw can be configured such that when screw 530 contacts the guiding device 520, the head of the screw forms a substantially flat surface with segment 510.

[0132] Typically, the pivot point adjustment element can be configured such that after the screw 530 has secured the segment 510 in the corresponding first position, the screw 530 can be loosened. Loosening the screw 530 loosens the segment 510, allowing the segment 510 to be moved to the corresponding second position. Moving the segment 510 to the corresponding second position moves the corresponding pivot point of the shoe to the corresponding second position.

[0133] Typically, when the screw enters from the side and / or mesial side of the body, Figure 5 The device shown for fixation is also applicable. For example, screw 530 can enter segment 510 from the side and / or the mesial side of the body.

[0134] Figure 6A and 6B Another embodiment of the rocker point adjustment element 600 is shown, wherein the means for fixing is based on a pin hole system. The rocker point adjustment element 600 includes segments 610 and rods 620a, 620b, 620c, 620d, and 620e, wherein rods 620a, 620b, 620c, 620d, and 620e are configured to guide the segments along a path. The rocker point adjustment element 600 also includes adjacent segments 630a and 630b, which are separated from segment 610 by corresponding gaps 640a and 640b.

[0135] Figure 6B A cross-section of the shoe and / or rocker point adjustment element is shown relative to a plane defined by points C and D (shown by a dashed line passing through points C and D). For example, this plane may be perpendicular to the direction of extension of the shoe. In particular, this plane may be perpendicular to the direction of extension of reinforcing elements (e.g., rods and / or plates). The plane defined by points C and D passes through pin 650a. The rocker point adjustment element 600 also includes a pin-hole system comprising at least two pins 650a, 650b and a plurality of holes. For example, a first portion of pin 650a may be disposed on the side of the shoe, and a second portion of pin 650b may be disposed on the mid-side of the shoe. Typically, the holes may be part of a segment 610. For example, segment 610 may include six holes 660a, 660b, 660c, 665a, 665b, and 665c. Specifically, holes 660a, 660b, and 660c of the first portion can be arranged on the side of the shoe body, and holes 665a, 665b, and 665c of the second portion can be arranged on the mid-side of the shoe. Typically, the number of holes on the side of the shoe body and the number of holes on the mid-side of the shoe can be the same. In some embodiments, the number of holes can be different. Typically, in different parts of the guiding device, there can be two or more pins to fix the segment and / or pivot point at a position along the path. For example, the number of holes arranged on the side of the shoe body and / or the mid-side can be two. Alternatively, the number of holes arranged on the side of the shoe body and / or the mid-side can be greater than three.

[0136] At least two pins 650a, 650b may typically be part of a guiding device, such as plate 610 and / or rods 620a, 620b, 620c, 620d, 620e. For example, pin 650a on the side of the shoe may be associated with rod 620a, and pin 650b on the midfoot of the shoe may be associated with rod 620e. Typically, holes 660a, 660b, 660c, 665a, 665b, and 665c, and pins 650a, 650b may be configured such that pins 650a, 650b can extend through the corresponding holes 660a, 660b, 660c, 665a, 665b, and 665c. When pins 650a and 650b extend through one of the corresponding holes, for example, when pin 650a extends through corresponding hole 660b and pin 650b extends through corresponding hole 665b, pins 650a and 650b can fix segment 610 in the corresponding first position. In particular, by fixing the first segment in the corresponding first position through pins 650a and 650b and holes 660a, 660b, 660c, 665a, 665b and 665c, the corresponding pivot point of the shoe can be fixed in the corresponding first position.

[0137] Furthermore, pins 650a and 650b can be configured such that they are movable relative to the extension direction of the corresponding holes. For example, pins 650a and 650b can be movable toward the center of the shoe. In particular, pins 650a and 650b can be pushed toward the center of the shoe. Pushing pins 650a and 650b toward the center of the shoe can release segment 610, making segment 610 movable relative to the path. Typically, when pins 650a and 650b spring into the hole corresponding to the second position, such as hole 660a or 660c, segment 610 can move from the first position to the second position and can be secured in the second position, thereby moving the corresponding pivot point of the shoe from the first pivot point position to the corresponding second pivot point position.

[0138] Figures 7A to 7C An embodiment of a rocker point adjustment element 700 disposed in a shoe is shown, and Figure 7D At least one fixing element 760a, 760b is shown in detail. The rocker point adjusting element 700 includes a segment 710 and a guiding device. In particular, the guiding device may include five rods, especially rod 720a. The rocker point adjusting element may further include adjacent segments 730a and 730b.

[0139] like Figure 7A As shown, segment 710 can be separated from the first adjacent segment 730a by a gap 740a. In addition, segment 710 can directly contact the second adjacent element 730b.

[0140] like Figure 7B As shown, segment 710 can be separated from the first adjacent segment 730a by a first gap 740a, and separated from the second adjacent segment 730b by a second gap 740b.

[0141] like Figure 7C As shown, segment 710 can be separated from the second adjacent segment 730b by a gap 740b, while being in direct contact with the first adjacent segment 730a.

[0142] Typically, the rocker point adjustment element may further include at least one screw 750 to secure the segment 710 in the corresponding first position.

[0143] Typically, the rocker point adjustment element 700 may also include at least one fixing element. For example, fixing elements 760a and / or 760b. At least one fixing element 760a, 760b may be configured to engage between segment 710 and at least one adjacent segment 730a, 730b. For example, fixing element 760a may be configured to engage between a first adjacent segment 730a and segment 710, and / or fixing element 760b may be configured to engage between a second adjacent segment 730b and segment 710.

[0144] Typically, different configurations (e.g., sizes) of the fixing elements 760a and / or 760b, and / or different positions of the fixing elements 760a and / or 760b within the shoe, can result in different pivot points for the shoe. For example, Figure 7A The arrangement of the fixing element 760a shown can result in—with Figure 7B The arrangement of the fixing elements 760a and 760b shown represents different pivot points of the shoe and can further lead to... Figure 7C The fixing element 760b shown is arranged at different shoe pivot points. Specifically, Figure 7A The pivot point of the shoe shown can be pushed to the back of the shoe. Figure 7A The pivot point of the shoe shown can be located in the area related to the middle of the shoe. Figure 7C The pivot point of the shoe shown can be pushed to the front of the shoe.

[0145] like Figure 7DAs best shown, the fixing elements 760a, 760b may include structures 762a, 762b, 762c, 762d, 762e, 762f, 764a, 764b, 764c, 764d, 764e compatible with the guiding means. For example, the fixing elements may include recesses 764a, 764b, 764c, 764d, 764e and / or fingers 762a, 762b, 762c, 762d, 762e, 762f compatible with the guiding means. Specifically, if the guiding device includes rods, such as rods 720a, 720b, 720c, 720d, 720e (which may be similar to rods 220a, 220b, 220c, 220d, 220e), then recesses 764a, 764b, 764c, 764d, 764e may be configured to receive a corresponding rod. For example, recess 764a may be configured to receive rod 720a.

[0146] Typically, the size and / or shape and / or number of fixing elements 760a, 760b are such that segment 710 is fixed in a corresponding first position. For example, if the first position of segment 710 results in a gap 740a, then the size and / or shape and / or number of fixing elements 760a, 760b may correspond to the size of gap 740a. Alternatively, if the first position of segment 710 results in gaps 740a and 740b, two fixing elements 760a and 760b may be used, wherein the size and / or shape of fixing element 760a may correspond to the size and / or shape of gap 740a, and / or the size and / or shape of fixing element 760b may correspond to the size and / or shape of gap 740b.

[0147] Figure 8A and 8BAn exemplary embodiment of a pivot point adjustment element disposed in a shoe 800 is shown. The pivot point adjustment element includes two segments 810a and 810b and a means 820 for guiding segments 810a and 810b along a path. Specifically, the guiding means 820 may include plates and / or rods. For example, the guiding means may include at least two rods, preferably at least three rods, and most preferably at least four rods. The shoe also includes adjacent segments 830a and 830b, which are separated from segments 810a and 810b by gaps 840a and 840b. Specifically, segment 810a is separated from segment 830b by gap 840a. Furthermore, segment 830a is separated from segment 810b by gap 840b, and segment 810b is separated from segment 830b by gap 840c. In some embodiments, adjacent segments 830a and 830b may be fixed. For example, adjacent segments may be immovable relative to the guiding device 820. Additionally or alternatively, adjacent segments 830a, 830b may be immovable relative to the shoe upper 860. In some embodiments, adjacent segments may be secured to the shoe upper 860. For example, segments 830a, 830b may be glued and / or sewn to the upper 860. Segments 810a, 810b include means for securing at least one segment. Specifically, segment 810a includes means 850a for securing segment 810a, and segment 810b includes means 850b for securing segment 810b. For example, the means 850a, 850b for securing may include screws and / or nuts and / or bolts.

[0148] Figure 8A A first configuration of segments 810a and 810b of shoe 800 is shown. Specifically, the first configuration of segments 810a and 810b is associated with a first configuration of the shoe's pivot point. For example, segment 810a is arranged in a portion of the shoe adapted to receive the rearfoot. The position of segment 810a may be associated with the shoe's rearfoot pivot point. Additionally or alternatively, segment 810b is disposed in a portion of the shoe adapted to receive the forefoot. The position of segment 810b may be associated with the shoe's forefoot pivot point. Based on the first configuration of segments 810a and 810b, the shoe may include a first rearfoot pivot point position and a first forefoot pivot point position.

[0149] Figure 8BA second configuration of segments 810a and 810b of shoe 800 is shown. The second configuration of segments 810a and 810b may differ from the first configuration of segments 810a and 810b. According to the second configuration, the position of segment 810a differs from the position of segment 810a in the first configuration. In other words, segment 810a has been moved along a path defined at least partially by the guiding device 820. Moving segment 810a from the first position to the second position may include: releasing the securing device 850a, and / or moving it along a path from the first position (see...) Figure 8A ) to the second position (see Figure 8B The segment 810a is moved along the path of the shoe 800, and / or secured in a second position by means of a fixing device 850a. Moving the segment 810a along the path may include moving the segment 810a toward the rear end of the shoe. For example, the segment 810a may be moved along a path toward the rear end of the shoe 800 such that at least a portion of the segment 810a extends at the end of the upper 860 of the shoe.

[0150] Typically, segment 810a is moved from the first position (see...) Figure 8A Move to the second position (see) Figure 8B The pivot point of the movable shoe 800 can be moved. Specifically, moving segment 810a from a first position to a second position can move the rearfoot pivot point of the shoe 800 from the first position to the second position. For example, by moving segment 810a towards the rear of the shoe, the rearfoot pivot point can be moved towards the rear of the shoe. Additionally or alternatively, moving segment 810a can also affect the forefoot pivot point of the shoe. For example, moving segment 810a can at least partially move the forefoot pivot point of the shoe 800.

[0151] Figure 8C A possible embodiment of the rocker point adjustment element is shown, wherein the guiding device 820 includes a position indicator 825. Specifically, the position indicator may indicate a first distance from segment 810b to adjacent segment 830a and / or a second distance from segment 810b to adjacent segment 830b. For example, the first and / or second distances may correspond to the dimensions of gaps 840b and 840c, respectively.

[0152] Figure 9A and 9BThis illustration shows a bottom side view of an exemplary rocker point adjustment element 900, which includes two laterally separated segments arranged in different configurations. The rocker point adjustment element 900 includes segments 910a and 910b laterally separated by a gap 950. Specifically, segment 910a is arranged in the body-side region of the rocker point adjustment element 900, and segment 910b is arranged in the proximal region of the rocker point adjustment element 900. Segments 910a and 910b may include different shapes and / or different sizes. For example, segments 910a and 910b include five sides. In some embodiments, the number of sides may be greater. Alternatively, the number of sides may be smaller; for example, segments 910a and / or segment 910b may include four sides. Typically, the number of sides of segment 910a may differ from the number of sides of segment 910b. Segments 910a and 910b can be independently movable; for example, the position of segment 910a can be changed independently of the position of segment 910b. The rocker point adjustment element 900 also includes adjacent segments 930a and 930b, which are separated from segments 910a and 910b by gaps 940. Specifically, the configuration of gaps 940 can be based on the positions of segments 910a and 910b. For example, segment 910a can be positioned with a gap 950 between it and adjacent segment 930a, and also with a gap 950 between it and adjacent segment 930b. Similarly, segment 910b can be positioned with a gap 950 between it and adjacent segment 930b, but in contact with adjacent segment 930a. The rocker point adjustment element 900 also includes four rods 920a, 920b, 920c, and 920d. Specifically, the first set of rods 920a and 920b extends through segment 910a. The first set of rods 920a and 920b at least partially defines the path of segment 910a. For example, segment 910a can move along the path defined at least partially by the first set of rods 920a and 920b. Furthermore, the second set of rods 920c and 920d extends through segment 910b. The second set of rods 920c and 920d at least partially defines the path of segment 910b. For example, segment 910b can move along the path defined at least partially by the second set of rods 920c and 920d. In particular, the path defined by the first set of rods 920a and 920b can be substantially parallel to the path defined by the second set of rods 920c and 920d. In some embodiments, the two paths may not be parallel, but may include different orientations and / or different directions.

[0153] In some embodiments, the rocker point adjustment element may include at least three, preferably at least four laterally spaced segments. For example, each lever 910a, 910b, 910c, 910d may guide a segment laterally separated from the other levers 910a, 910b, 910c, 910d. For example, lever 910a may extend through a first segment and guide the first segment along a first path. Additionally or alternatively, lever 910b may extend through a second segment and guide the second segment along a second path. Additionally or alternatively, lever 910c may extend through a third segment and guide the third segment along a third path. Additionally or alternatively, lever 910d may extend through a fourth segment and guide the fourth segment along a fourth path. Specifically, there may be a correspondence between the number of levers and the number of laterally spaced segments in the rocker point adjustment element.

[0154] Additionally or alternatively, rods 910a, 910b, 910c, and 910d may define a group of rods. A group of rods may include at least one rod 910a, 910b, 910c, or 910d. A group of rods may be associated with segments 910a and 910b. Associating with a segment may include: the rods in the group extending through the segment. Additionally or alternatively, associating with a segment may include: the rods in the group guiding the segment along a path.

[0155] according to Figure 9A The arrangement of segments 910a and 910b can be associated with the first pivot point of the shoe. For example, the arrangement of segments 910a and 910b can be associated with the first forefoot pivot point of the shoe. Furthermore, according to... Figure 9B The arrangement of segments 910a and 910b can be associated with a second pivot point of the shoe. For example, the arrangement of segments 910a and 910b can be associated with a second forefoot pivot point of the shoe. Specifically, moving the pivot point of the shoe from a first forefoot pivot point position to a second forefoot pivot point position can include: moving segment 910a along a path defined by the first set of rods 920a and 920b, and / or moving segment 910b along a path defined by the second set of rods 920c and 920d. For example, segment 910a can move towards the rear end of the shoe along the path defined by rods 920a and 920b. In particular, segment 910a can move towards the rear end to contact an adjacent segment 930a. The position of segment 910a that contacts the adjacent segment 930a can include the rearmost position of segment 910a. Additionally or alternatively, segment 910b may move toward the foreground of the shoe along the path defined by rods 920c and 920d. Specifically, segment 910b may move forward to be longitudinally spaced from adjacent segments 930a and 930b. In other words, segment 910b may be moved to create a gap relative to adjacent segments 930a and 930b.

[0156] The shoe includes a pivot point adjustment element comprising longitudinally and laterally spaced segments 910a and 910b (longitudinal gap 940 and lateral gap 950), allowing for minute adjustments to the pivot point. Specifically, the pivot point adjustment element, comprising longitudinally and laterally spaced segments 910a and 910b—associated respectively with the lateral and mesial sides of the body—allows for minute adjustments to the pivot point. Allowing for minute adjustments to the pivot point enhances its adaptability to the athlete's individual needs.

[0157] Figures 10A to 10C A bottom side view of an exemplary rocker point adjustment element 1000 is shown, wherein a segment is displaced relative to two paths according to different configurations. The rocker point adjustment element 1000 includes a segment 1010 and two rods 1020a, 1020b. The rocker point adjustment element 1000 also includes means 1050a, 1050b for securing the segment 1010. For example, the means 1050a, 1050b for securing may be configured to secure the segment 1010 relative to the rods 1020a, 1020b and / or relative to adjacent segments 1030a, 1030b. In some embodiments, the means 1050a, 1050b for securing may include screws. The rods 1020a, 1020b may be at least partially contained in the segment 1010 and / or at least partially extend through the segment. Specifically, rods 1020a and 1020b may not extend through a portion of adjacent segments 1030a and 1030b.

[0158] Typically, rod 1020a can guide segment 1010 along a first sub-path, and rod 1020b can guide segment 1010 along a second sub-path. The first and second sub-paths can be parallel paths. Additionally or alternatively, the first and second sub-paths can include different orientations; for example, the orientations of the first and second sub-paths can form an angle, and / or the orientation of the first sub-path can be opposite to the orientation of the second sub-path.

[0159] Typically, the rocker point adjustment element 1000 can be configured such that segment 1010 can move at least along a path. For example, the first path may include a configuration in which a first sub-path defined by rod 1020a is parallel to a second sub-path defined by rod 1020b. In particular, moving segment 1010 along the first path allows segment 1010 to move in the longitudinal direction of the shoe and / or the rocker point adjustment element 1000.

[0160] Additionally or alternatively, the second path may include a configuration in which the orientation of the first sub-path defined by rod 1020a may be opposite to the orientation of the second sub-path defined by rod 1020b. For example, moving segment 1010 along the second path may include moving a first portion of segment 1010 along the first sub-path defined by rod 1020a and a second portion of segment 1010 along the second sub-path defined by rod 1020b. In particular, moving the first portion of segment 1010 along the first sub-path may include moving the first portion of segment 1010 by a first amount in a first direction / orientation. Additionally or alternatively, moving the second portion of segment 1010 along the second sub-path may include moving the second portion of segment 1010 by a second amount in a second direction / orientation. For example, the first direction / orientation may be opposite to the second direction / orientation. For example, the first direction / orientation may point towards the rear end of the shoe and / or rocker point adjustment element 1000, while the second direction / orientation may point towards the front end of the shoe and / or rocker point adjustment element 1000.

[0161] Moving segment 1010 according to the second path may include causing twisting of segment 1010 relative to the shoe and / or rocker point adjustment element 1010. Typically, causing twisting of segment 1010 may include adjusting the geometry and / or dimensions of gaps 1040a, 1040b. Additionally or alternatively, causing twisting of segment 1010 may include adjusting the rocker point of the shoe. Specifically, causing twisting of segment 1010 may include adjusting the forefoot rocker point and / or the rearfoot rocker point of the shoe.

[0162] like Figure 10A As shown, segment 1010 can be separated from adjacent segment 1030a by a gap 1040a. For example, gap 1040a can make the distance between segment 1010 and adjacent segment 1030a constant. In other words, the boundary of segment 1010 and the boundary of adjacent segment 1030a can be substantially parallel. Additionally or alternatively, gap 1040b can make the distance between segment 1010 and adjacent segment 1030b constant. In other words, the boundary of segment 1010 and the boundary of adjacent segment 1030b can be substantially parallel. Figure 10A The first configuration of segment 1010 may include the first position of the shoe pivot point (specifically the forefoot pivot point of the shoe).

[0163] Figure 10B A second configuration of segment 1010 is shown. Segment 1010 can be separated from adjacent segment 1030a by a gap 1040a, wherein the gap 1040a is relative to the second configuration (see [reference]). Figure 10B The geometry and / or dimensions of the gap 1040a may differ from those of the first configuration (see [reference]). Figure 10AThe geometry and / or dimensions of segment 1010. Specifically, the distance between segment 1010 and adjacent segment 1030a can vary relative to the lateral direction. For example, segment 1010 may contact adjacent segment 1030a on the side of the shoe, and the degree of separation and / or the size and / or distance of the gap may increase towards the midline of the shoe. In other words, the boundary of segment 1010 and the boundary of adjacent segment 1030a may not be parallel; for example, they may intersect at an angle.

[0164] Additionally or alternatively, segment 1010 may be separated from adjacent segment 1030b by a gap 1040b, wherein the gap 1040b is relative to the second configuration (see...). Figure 10B The geometry and / or dimensions of the gap 1040b relative to the first configuration may differ from those of the first configuration (see [link]). Figure 10A The geometry and / or dimensions of segment 1010. Specifically, the distance between segment 1010 and adjacent segment 1030b can vary relative to the lateral direction. For example, segment 1010 may contact adjacent segment 1030b near the midline of the shoe, and the degree of separation and / or the size and / or distance of the gap may increase toward the lateral side of the shoe. In other words, the boundary of segment 1010 and the boundary of adjacent segment 1030b may not be parallel; for example, they may intersect at an angle.

[0165] For example, the first configuration of segment 1010 (see Figure 10A ) changed to the second configuration of segment 1010 (see Figure 10B This may include: moving segment 1010 according to a second path, for example, moving the body-side portion of segment 1010 towards the rear end of the shoe along a sub-path defined by rod 1020a, and / or moving the proximal portion of segment 1010 towards the front end of the shoe along a sub-path defined by rod 1020b. The first configuration of the segment (see...) Figure 10A Change to the second configuration of segment 1010 (see...) Figure 10B This may include changing the shoe's pivot point from a first position to a second position. In particular, the shoe's forefoot pivot point may be changed from the first position to the second position.

[0166] Figure 10C The third configuration of segment 1010 is shown. The third configuration of segment 1010 can be associated with the third position of the rocker point of the shoe, and in particular with the third position of the rocker point of the forefoot of the shoe.
