[0002] shoe sole

[0003] Technical area

[0004] The invention relates to a shoe sole suitable for a footwear article according to the preamble of claim 1.

[0005] State of the art

[0006] From the publication WO 2013 05 68 64 A1, a shoe sole according to the preamble of claim 1 is known. This known shoe sole has an insole designed to support a physiological gait, i.e., a natural or correct gait.

[0007] In a natural or correct gait, the feet alternately touch the ground, with the foot either initially touching the ground with its heel or simultaneously touching the ground with its heel and midfoot. The foot then begins to roll on the ground with a slight deformation, with its heel, midfoot, ball, and forefoot coming into contact with the ground. In doing so, the foot defines a ground contact line, or more precisely, a gait line, akin to a physiological gait line.

[0008] Optimally, i.e. in a person with healthy bones, tendons, muscles and nerves and a natural gait, this gait line is typically an essentially / approximately S-shaped line on the sole of each foot. An optimal gait line begins at the heel section, runs along the metatarsal and ball of the foot sections and ends at the forefoot section, typically on the medial side of the forefoot section in the area of ​​the first and second metatarsal parts and the first and second toes. In order to support the wearer of the shoe sole in their proprioception of the foot, i.e. their perception of the position of the foot in space, in particular their perception of the gait line, WO 2013 05 68 64 A1 provides a shoe sole which has an insole that is narrower than the shoe sole, wherein the insole extends along an S-shaped line of the shoe sole.To promote proprioception and control optimal foot movement, this well-known insole is made of a harder material than the surrounding shoe sole material. Following the principles of Newton's third law, the harder insole creates a counterpressure that counteracts the pressure exerted by the foot on the sole when walking.

[0009] Furthermore, a modular insole system for shoe soles is known from WO 2016 09 23 53 A1. This modular insole system comprises a relatively soft, resilient midsole and hard insert elements designed to be inserted into vertical cavities of the midsole. By varying the hardness of the inserts in the various vertical cavities, the user's natural or correct gait can be supported. In particular, pronation—that is, an inward rotation of the foot in which the lateral foot area is raised and the medial foot area is lowered—is adapted to the wearer's gait.

[0010] Description of the invention: task, solution, advantages

[0011] The invention is based on the object of further developing a shoe sole of the type mentioned above in such a way that the shoe sole further supports the user's natural or correct gait. The shoe sole is intended to optimize the perception of the optimal gait line. In particular, the shoe sole is intended to guide the user's foot to the optimal gait line.

[0012] This object is achieved by a shoe sole having the features specified in claim 1 and by a shoe sole having the features specified in claim 14. Advantageous embodiments and expedient further developments of the present invention are characterized in the respective dependent claims. Thus, the present invention is based on designing the guide element or at least one of the guide elements as a proprioceptive guide element with elevations extending towards the foot contact surface, wherein the elevations are arranged at least in regions along the S-shaped line and are designed to impart localized increases in pressure to the foot of the wearer of the shoe sole. The proprioceptive guide element is thus designed to impart a locally limited increase in pressure to the wearer's foot, at least in regions along the S-shaped line.

[0013] The S-shaped line in this case is an imaginary line that runs centrally through the physiological gait line. In this case, the physiological gait line is understood to be the ground contact line of the foot during natural or correct gait. This line begins at the heel and runs in an S-shape from a region of the heel located medially to the center of the foot, along the metatarsal and ball of the foot, and ends at the forefoot. In the metatarsal section, the S-shaped line typically runs through a region of the metatarsal section located lateral to the center of the foot and then runs centrally through the ball of the foot and then through a region of the ball of the foot located medially to the center of the foot.At the forefoot section, the S-shaped line typically ends on a side of the forefoot section medially to the middle of the foot in the area of ​​the first and second metatarsal parts and the first and second toes.

[0014] In order to provide the wearer's foot with a locally limited increase in pressure, at least in some areas along the S-shaped line, the elevations are arranged at least in some areas along the S-shaped line, for example in the heel section of the S-shaped line, in the ball section of the S-shaped line, and in the forefoot section of the S-shaped line. The localized pressure increases promote the user's foot proprioception while walking, in particular the perception of the optimal gait line. The elevations activate and stimulate the foot. The proprioceptive guidance element thus guides the foot to the physiological gait line because the foot follows the localized pressure increases.

[0015] Independently of this or in connection herewith, the present invention is based on the fact that the shoe sole has, in the heel section arranged medially to the essentially S-shaped line, a stabilization element which is detachably fastened in the shoe sole and extends from the shoe sole towards and up to the level of the ground contact surface. In the present case, the transition area between the heel section and the midfoot section is also referred to as the heel section. The stabilization element serves to regulate the proprioception of the foot when walking, for example, to regulate the intensity of the perception of the gait line. Since intensive proprioception of the foot when walking over a longer period of time can be strenuous or tiring for the user, it is helpful if the stabilization element can be used to relieve the foot as needed.By means of the stabilization element, the intensity of proprioception, in particular the intensity of the perception of the optimal gait line, can be optimized as needed.

[0016] If the stabilization element is attached to the shoe sole, it supports the medial inner area of ​​the heel section. This stabilizes the hindfoot, or heel bone, regulates foot pronation, and slightly reduces the intensity of foot proprioception when walking. The stabilization element thus guides the foot to the physiological gait line and controls the optimal movement sequence of the foot. With the stabilization element inserted, the wearer of the shoe sole needs to walk less actively, i.e., activate the foot muscles less, since the stabilization element supports the heel bone medially. To promote proprioception, in an advantageous embodiment of the present invention, the ground contact surface has a smaller width than the shoe sole. Therefore, both the proprioceptive guidance element and the ground contact surface preferably extend along the S-shaped line.In other words, in this advantageous embodiment, the ground contact surface in the midfoot section comprises a recess medially and laterally.

[0017] Advantageously, the shoe sole comprises at least one midsole, for example, a sole body or body, wherein the proprioceptive guidance element and the ground contact surface are narrower than the midsole. The width of the proprioceptive guidance element and the ground contact surface is therefore preferably smaller than the width of the midsole or sole body.

[0018] In particular, the heel portion of the ground contact surface and of the proprioceptive guide element has an area that is, for example, at least 1 / 20, approximately at least 1 / 10, preferably at least 1 / 8, smaller than the heel portion of the midsole.

[0019] The heel section of the ground contact surface and the proprioceptive guidance element thus has a recess compared to the heel area of ​​the midsole. This recess surrounds the heel section and is also formed in the medial inner region of the heel section. In the area of ​​the recess, which is arranged in the medial inner region of the heel section, the shoe sole preferably has a receiving element designed to accommodate the stabilization element. For example, the ground contact surface of the heel section can fill approximately 1 / 2 of the ground contact surface of the heel section, and the receiving element designed to accommodate the stabilization element can fill approximately 1 / 2 of the ground contact surface of the heel section.Furthermore, the midfoot section of the ground contact surface and of the proprioceptive guide element has a surface area that is, for example, at least 1 / 4, approximately at least 1 / 3, preferably at least half, smaller than the midfoot section of the midsole.

[0020] The ball of the foot section of the ground contact surface and of the proprioceptive guide element advantageously has an area, for example by at least 1 / 20, approximately by at least 1 / 15, preferably by at least 1 / 10, smaller than the ball of the foot section of the midsole.

[0021] The forefoot section of the ground contact surface and the proprioceptive guidance element has a surface area that is, for example, at least 1 / 3, approximately at least half, and preferably at least 3 / 5 smaller than the forefoot section of the midsole. Thus, the forefoot section of the ground contact surface and the proprioceptive guidance element can be approximately the width of a big toe, and the forefoot section can be the width of the entire forefoot.

[0022] The narrower design of the proprioceptive guidance element and the ground contact surface compared to the midsole cause transverse instability, in other words, a tendency toward a rolling or tilting movement of the foot around its longitudinal axis when walking or running. This transverse instability promotes the natural or correct gait and the proprioception of the user's foot.

[0023] In an embodiment in which both the proprioceptive guidance element and the ground contact surface extend along the S-shaped line, the stabilization element is particularly helpful for relieving the foot during fatigue. The stabilization element according to the invention stabilizes the shoe sole in the area of ​​the heel section or rearfoot when walking, but does not completely reduce the transverse instability. This means that the transverse instability remains in a somewhat reduced form. In contrast, a shoe sole in which the ground contact surface extends across the entire width of the shoe, such as the shoe sole known from WO 2016 09 23 53 A1, exhibits no transverse instability.

[0024] According to the invention, the stabilizing element is arranged in the heel section or heel area. This has the advantage that the shape and size of the ground contact surface of the shoe sole remain unchanged, regardless of whether the stabilizing element is inserted into the shoe sole or not.

[0025] To further enhance proprioception, the proprioceptive guidance element can be made of a harder material, in particular of at least one harder elastomer, than the shoe sole material surrounding the proprioceptive guidance element. For example, the proprioceptive guidance element can be made of at least one material selected from the group of thermoplastic polyurethanes (TPU), and the shoe sole material surrounding the proprioceptive guidance element, in particular the material of the midsole, can be made of at least one softer elastomer, for example, a material selected from the group of polyurethanes (PU) and / or ethylene vinyl acetates (EVA).

[0026] In a preferred embodiment of the present invention, the hardness of the proprioceptive guide element is in the range of about 75 Shore to about 90 Shore, for example from about 81 Shore to about 90 Shore, and the hardness of the midsole is in the range of about 40 Shore to about 70 Shore and / or the hardness of the ground contact surface is in the range of about 40 Shore to about 70

[0027] Shore.

[0028] The hardness of the stabilizing element is advantageously in a range from approximately 20 Shore to approximately 95 Shore, preferably between 50 Shore and 90 Shore. The harder the stabilizing element, the more medially stable the shoe sole is.

[0029] The proprioceptive guidance element and / or the midsole and / or the ground contact surface can have a uniform hardness or varying hardness within the aforementioned ranges. Furthermore, the proprioceptive guidance element and / or the midsole and / or the ground contact surface can have a uniform thickness or vary in thickness.

[0030] In other words, as described in the document WO 2013 05 68 64 A1, the shoe sole may comprise first sole portions extending along the S-shaped line and second sole portions extending along both sides of the substantially S-shaped line.

[0031] In the present case, the shoe sole can therefore comprise the proprioceptive guide element and the outsole as the first sole sections, as well as optionally the stabilizing guide element and areas of further sole elements arranged in a vertical plane with the proprioceptive guide element, such as areas of the midsole extending along the S-shaped line.

[0032] As second sole sections, the shoe sole can comprise the outsole and optionally areas of other sole elements that are laterally adjacent to the proprioceptive guide element, such as the midsole.

[0033] The local thickness and / or hardness of a first sole section, for example, the proprioceptive guidance element and / or the stabilizing guidance element, can be greater than the local thickness and / or hardness of a second sole section, for example, the midsole, adjacent to the first sole section. In this case, the local thickness and / or hardness of the proprioceptive guidance element and / or the stabilizing guidance element, for example, located in the region of the S-shaped line, can be greater than the local thickness and / or hardness of the midsole.

[0034] For example, as described in WO 2013 05 68 64 A1, the local thickness of a first sole section can be greater than the local thickness of a second sole section adjacent to the first sole section, wherein the first sole section and the second sole section have the same hardness. Thus, the local thickness of the proprioceptive guidance element and / or the stabilizing guidance element can be greater than the local thickness of the midsole, wherein the proprioceptive guidance element and / or the stabilizing guidance element have the same local hardness as the midsole.

[0035] Furthermore, the local hardness of the proprioceptive guide element and / or the stabilizing guide element can be greater than the local hardness of the midsole, wherein the proprioceptive guide element and / or the stabilizing guide element has the same local thickness as the midsole.

[0036] The difference in local thickness and / or hardness between the proprioceptive guidance element and the midsole and / or the stabilizing guidance element and the midsole can be greatest in the midfoot section, which extends between the heel and the ball of the foot. Such a distribution of local thickness and / or hardness provides the wearer's foot with a further localized increase in pressure along the S-shaped line, thus enhancing the proprioceptive effect.

[0037] Furthermore, in an advantageous embodiment of the present invention, the height and / or thickness of the outsole in the medial region of the heel portion can be thicker or higher, for example by approximately 1 mm to 1.5 mm, than in the lateral region of the heel portion, and / or

[0038] - be lower in the medial area of ​​the ball of the foot, for example by approximately 1 mm to 2 mm, than in the lateral area of ​​the ball of the foot and / or

[0039] - in the medial area of ​​the forefoot, for example, be approximately 1 mm to 2 mm lower than in the lateral area of ​​the forefoot. This ensures optimal guidance of the foot to the physiological gait line.

[0040] Alternatively, or in conjunction with this, the shoe sole can comprise, in addition to the proprioceptive guidance element, another guidance element extending along an S-shaped line, for example, at least one stabilizing guidance element. The stabilizing guidance element is arranged between the ground contact surface and the proprioceptive guidance element, in particular between the ground contact surface and the midsole. To control the optimal movement of the foot, the additional guidance element is made of a harder material than the shoe sole material, which surrounds the additional guidance element laterally, or which therefore extends along both sides of the essentially S-shaped line (G).For example, the proprioceptive guide element with the elevations can be made of at least one material selected from the group of polyurethanes (PU) and / or ethylene vinyl acetates (EVA) and / or thermoplastic polyurethanes (TPU) and the stabilizing guide element can be made of at least one material selected from the group of thermoplastic polyurethanes (TPU).

[0041] The stabilizing guide element stabilizes the shoe sole so that it always returns to its original shape despite deformation during walking. Furthermore, the stabilizing guide element supports the proprioceptive guide element and, based on the interaction principle, provides counterpressure to the pressure exerted by the elevations of the proprioceptive guide element on the stabilizing guide element. The stabilizing guide element thus interacts with the proprioceptive guide element in such a way that the localized pressure increases caused by the elevations are amplified. The proprioceptive guide element and the stabilizing guide element thus synergistically support the pressure line of the foot upon ground contact, providing information for the physiological gait pattern.

[0042] In an advantageous embodiment, the hardness of the stabilizing guide element is at least 80 Shore, preferably above 80 Shore, for example, in the range from approximately 81 Shore to approximately 98 Shore. The stabilizing guide element can have a uniform hardness or varying hardnesses within the aforementioned ranges. Furthermore, the stabilizing guide element can have a uniform thickness or vary in thickness.

[0043] In an advantageous embodiment, the proprioceptive guidance element is harder than the midsole, but softer and thus more dynamic, or in other words, more flexible, than the stabilizing guidance element. In this case, the proprioceptive guidance element transmits the hardness information of the stabilizing guidance element to the foot. The interaction of the outsole, stabilizing guidance element, midsole, and proprioceptive guidance element controls the intensity of the perception of the optimal gait line.

[0044] In an advantageous embodiment of the present invention, in addition to the proprioceptive guide element, the stabilizing guide element can also have elevations extending to the foot contact surface, which are designed to impart a localized increase in pressure to the foot of the wearer of the shoe sole. These elevations are advantageously arranged analogously to the elevations of the proprioceptive guide element. As a result, increased pressure is provided by the shoe sole. The perception of proprioception and guidance to the physiological gait line are thus enhanced. The elevations designed for localized pressure increase are preferably located in the area of ​​the heel section, the ball section, and the forefoot section. Advantageously, the elevations are therefore arranged along the S-shaped line, with the midfoot section being free of elevations.Feedback on ground contact when walking in the heel, ball and forefoot areas is particularly helpful in supporting the user's natural or correct gait.

[0045] The raised areas can, for example, be shaped like spherical segments. Spherical segments provide particularly comfortable wear and optimally stimulate blood circulation in the foot.

[0046] By varying the size, particularly the height and / or volume, of the elevations, the foot can be guided to the optimal gait line. The pressure points of elevations of varying heights can thus partially guide the foot to where it should roll. For example, the height of the pressure points can vary within a range of approximately 0.2 mm to approximately 4 mm, preferably within a range of approximately 1 mm to approximately 2 mm. For example, small elevations can be provided with a height of approximately 1 mm, medium elevations with a height of approximately 1.5 mm, and large elevations with a height of approximately 2 mm.

[0047] In order to guide the user's foot to the optimal gait line, in an advantageous embodiment of the present invention the elevations in a heel area arranged medially of the essentially S-shaped line, i.e. in the heel area on the inside of the foot, have a lower height and / or a lower volume than the elevations in a heel area arranged laterally of the essentially S-shaped line. The term "arranged medially of the essentially S-shaped line" is understood here to mean an area which, from the perspective of the S-shaped line, is arranged towards the inside of the foot. The term "arranged laterally of the essentially S-shaped line" is understood here to mean an area which, from the perspective of the S-shaped line, is arranged towards the outside of the foot.

[0048] Independently of or in conjunction with this, in order to guide the user's foot to the optimal gait line, the elevations in a ball of the foot portion medially located from the substantially S-shaped line may have a greater height and / or a greater volume than the elevations in a ball of the foot portion laterally located from the substantially S-shaped line.

[0049] To ensure the shoe sole has an even better rolling action, recesses, particularly U-shaped or V-shaped notches, can be arranged in the outsole, or in the outsole and midsole. These recesses extend from a side of the outsole located medially towards the middle of the foot to a side of the outsole located laterally towards the middle of the foot, for example transversely to the shoe sole or perpendicular to the S-shaped line. The width of the recesses corresponds to the width of the proprioceptive guidance element. Along the longitudinal direction of the S-shaped line (G), the recesses are arranged at least in the heel section, the midfoot section, and the ball of the foot section. The recesses are spaced apart from one another in the longitudinal direction. The longitudinal spacing of the recesses can be regular or irregular, i.e., the spacing can vary.The cutouts can extend in straight lines from one side of the shoe sole to the other. Alternatively, the cutouts can also run as curved or folded lines, for example, in a C-shape, between the two sides of the outsole. The cutouts are preferably located exclusively on the S-shaped line. The cutouts cause a dynamic rolling motion of the shoe sole instead of a continuous rolling motion. The shoe sole rolls more easily, thus becoming more flexible. This requires the wearer to stabilize more.

[0050] The present invention further relates to a shoe sole of the type described above for gait correction or gait maintenance, in particular for the therapeutic treatment of foot deformities when walking.

[0051] Finally, the present invention relates to a shoe comprising a shoe sole of the type described above.

On the other hand, further embodiments, features, and advantages of the present invention are explained in more detail below, inter alia, with reference to the two exemplary embodiments illustrated in Figures 1 to 8.

[0062] Fig. 8 shows a side view of the shoe sole from Figure 7. Identical or similar configurations, elements or features are provided with identical reference numerals in Figures 1 to 8.

[0063] Best way of carrying out the invention

[0064] In the two embodiments of the present invention illustrated with reference to Figures 1 to 8, a shoe sole suitable for footwear is shown, which is designed for gait correction or gait maintenance, in particular for preventive support and for therapeutic treatment of the physiological gait pattern.

[0065] As shown in Figure 1, the shoe sole 100 comprises, on its ground contact surface 12 of its outsole 10, a heel section 3, a midfoot section 4, a ball of the foot section 5, and a forefoot section 6 in a sequence running from a rear to a front end along the shoe sole 100. The heel, midfoot, and ball of the foot sections each border an arch area below the arch of a foot 2 when wearing the shoe sole 100. The outsole can, for example, be designed as a durable anti-slip sole, which provides good grip even on wet roads.

[0066] Furthermore, the shoe sole 100 comprises at least one substantially S-shaped guide element 40, 41 embedded between the ground contact surface 12 and a foot contact surface of the shoe sole 100 and designed to control the optimal movement sequence of the foot. In other words, the guide element 40, 41 extends along a substantially S-shaped line (G) that begins at the heel section 3, runs along the midfoot section 4 and ball of the foot section 5, and ends at the forefoot section 6.

[0067] In the embodiments shown in Figures 1 to 8, the shoe sole 100 has a first guidance element, namely a proprioceptive guidance element 40 with elevations 42, 44 extending toward the foot contact surface (see Figures 2 and 4). This essentially S-shaped proprioceptive guidance element 40 supports the pressure line of the foot 2 upon contact with the ground, providing information for the physiological gait pattern. Furthermore, the pressure points serve to stimulate and improve blood circulation, thus providing a gentle massage.

[0068] With regard to its properties, in particular with regard to the distribution of its hardness and / or its thickness as well as its arrangement in the shoe sole, and its shape, the proprioceptive guide element 40 can be designed like the second or upper insole described in the document WO 2013 05 68 64 A1.

[0069] In addition, the shoe sole 100 has a further guide element 41 arranged between the ground contact surface 12 and the proprioceptive guide element 40, namely a stabilizing guide element 41, for example a leading stability element, which is made of a harder material than the shoe sole material surrounding the guide elements 40, 41. The local thickness and / or the local hardness of the stabilizing guide element 41 is thus greater than the local thickness and / or the local hardness of the material of the shoe sole 100 surrounding the guide elements 40, 41, in particular laterally.

[0070] The stabilizing guide element 41 always guides the shoe back to its original position, thus preventing it from becoming tilted. For this purpose, the stabilizing guide element 41 is made of a harder material than a midsole 20.

[0071] With regard to its properties, in particular with regard to the distribution of its hardness and / or its thickness as well as its arrangement in the shoe sole and its shape, the stabilizing guide element 41 can be designed like the first insole described in the document WO 2013 05 68 64 A1.

[0072] The material surrounding the guide elements 40, 41 is assigned to the midsole 20 of the shoe sole 100. This midsole 20 can be designed, in terms of its properties—in particular, its shape, material, functions, and advantages—like the base body described in WO 2013 05 68 64 A1. The midsole 20 can be made of polyurethane, for example. The density of polyurethane enables high elasticity and provides a very pleasant feeling for the wearer of the shoe sole. Furthermore, polyurethane is durable and remains stable even when exposed to heat and cold.

[0073] The guide elements 40, 41 are integrated into the midsole 20 in the state of use, for example glued to the midsole 20 or cast into the midsole.

[0074] The guide elements 40, 41 have a smaller width than the midsole 20. As shown in Figure 1, the ground contact surface 12 advantageously has the same shape as the at least one guide element 40, 41.

[0075] Figures 1 to 6 thus show a shoe sole with an outsole 10, a midsole 20, and at least one substantially S-shaped guide element 40, 41. The outsole 10 has a substantially S-shaped ground contact surface 12. At least one of the guide elements 40, 41 is harder than the material of the shoe sole 100, which laterally surrounds the at least one substantially S-shaped guide element 40, 41. The ground contact surface 12 and the guide element 40, 41 are both narrower than the midsole 20 and shaped such that they extend along the S-shaped line G.

[0076] The ground contact surface 12 is designed to cause transverse instability of the foot 2 during walking or running. The at least one guide element or at least one of the guide elements 40, 41 is designed to impart a locally limited increase in pressure along the gait line to the wearer's foot 2.

[0077] The outsole 10 further includes a removable stabilization element 50, which is designed to provide additional ground contact in the heel section 3 and medially to the ground contact surface 12. The stabilization element 50 can be optionally inserted or removed to increase the lateral stability of the foot when walking or running. In this case, lateral stability of the foot refers to the stability of the foot around its longitudinal axis. Thus, lateral stability counteracts a tendency of the foot to roll around its longitudinal axis.

[0078] A cross-section through the heel area of ​​a shoe sole 100 suitable for a left shoe is shown in Figure 4.

[0079] The stabilizing element 50 can, for example, be made of at least one material selected from the group of thermoplastic polyurethanes (TPU).

[0080] The stabilization element 50 guides the rearfoot or heel bone by providing support for the shoe during torsion. Thus, the stabilization element 50 always guides the rearfoot back to its natural, original position. The stabilization element 50 thus prevents the foot from prematurely bending, twisting, or deforming.

[0081] Laterally outward, the ground contact surface 12 is also narrower than the shoe sole 100 in the heel area 3. Thus, transverse instability remains in the heel area despite the stabilization element 50.

[0082] To accommodate the stabilization element 50, the outsole 10 advantageously has a receiving element 14. As shown in Figure 6, the receiving element 14 can have a fastening means 16, which is designed to interact with a complementary fastening means 52 of the stabilization element 50 such that the stabilization element 50 can be releasably fastened in the receiving element 14. Furthermore, the stabilization element 50 can also be held in the shoe sole by means of at least one plug connection and / or by means of at least one screw connection. As described above and shown in Figures 2 and 4, the at least one guide element or at least one of the guide elements 40, 41 can have a plurality of proprioception-promoting elevations or projections 42, 44 on its surface facing the foot 2. These proprioception-promoting elevations 42, 44 can, for example, be bubble-shaped.The elevations can, for example, be formed in two or three different sizes, allowing the foot to be guided toward the gait line G. The proprioceptive guide element 40, 41 is preferably formed integrally with the proprioception-promoting elevations 42, 44.

[0083] The second embodiment of the shoe sole according to the present invention, shown in Figures 7 and 8, differs from the embodiment shown in Figures 1 to 6 in that recesses 18, for example U-shaped or V-shaped transverse notches, such as transverse flexion grooves, are arranged in the outsole and midsole. These recesses 18 run transversely to the S-shaped line in the forefoot area and cause the shoe sole to become somewhat more flexible and roll more easily.

[0084] The notches can have a depth of at least 2 mm to a maximum of 1 cm extending from the ground contact surface 12 to the midsole 20. Furthermore, the notches on the ground contact surface can have a width of 1 mm to 1 cm. The longitudinal spacing of the recesses can be, for example, between 1 mm and 10 mm, preferably between 1 mm and 6 mm.

[0085] The shoe sole shown in Figures 1 to 8 enables the wearer to achieve an improved rolling motion and thus a more upright and healthy gait.
