Description

1. Technical field

[0001] The present invention relates to a sole, in particular a sole for a sports shoe for a young athlete, which includes a stabilizing element. The invention also relates to a sports shoe for a young athlete that includes this sole. 2. Technical Background

[0002] The development and construction of shoes is generally geared towards the needs of an adult, particularly an adult male with average feet. Through simple scaling, such standard shoes are typically also used for children of all ages. However, children, especially toddlers, have significantly different foot support needs due to the ongoing growth and development of their young bodies. These needs should be given particular consideration in the design and manufacture of soles, midsoles, and athletic shoes for young athletes, where support and stability are even more critical than in non-athletic footwear due to the higher demands of athletic activities.

[0003] To ensure a better anatomical fit for the wearer's foot, prior art document US 8,020,317 B1 discloses a shoe structure specifically designed to adapt more securely to a variety of foot widths and proportions through an integrated elastic heel device in the rearfoot area of ​​the upper. Furthermore, prior art document US 2018 / 0084864 A1 discloses a shoe with a stabilizer in the rearfoot area that suppresses lateral foot sway. Additionally, prior art document US 6,298,582 B1 discloses footwear, such as a running shoe, designed to provide a better and more anatomical fit to the wearer's foot to enhance performance and better arch support.The shoe features an articulated arch, a heel notch cut into the medial and lateral quarter panel, and a heel clamp instead of a traditional heel counter.

[0004] Document US 2010 / 0242304A1 relates to a footwear assembly comprising an upper and a sole assembly connected to the upper. The sole assembly includes a footwear assembly that comprises a sole assembly connected to an upper. The sole assembly includes a midsole made of a first material and having a forefoot area, an arch area, a heel area, and a sidewall extending around a lateral side, a medial side, and a heel side of the midsole.

[0005] Document DE 10 2015 121 670 A1 relates to a shoe comprising a lower part and an upper part, wherein the lower part is connected to the upper part, the upper part has an opening, and the lower part has at least on its inner side facing the foot and / or the upper part has at least on its inner side facing the foot at least an area that increases the coefficient of friction.

[0006] Document US 2001 / 0018805A1 concerns a sole assembly for boots suitable for a variety of sporting activities, allowing the user to customize their boot depending on the sport. A flexible sole is connected to a footrest, which includes a fastening device that allows the footrest to be detachably attached to the underside of the sole.

[0007] Document US 8,468,721 B2 relates to a shoe construction specifically designed to more securely accommodate a wider range of foot widths and proportions through an integrated, elastic heel device in the rearfoot area of ​​the upper. The heel device extends upward and backward toward the instep to avoid the bulbous end of the heel bone, but also to encompass the area directly above the heel bone. The heel device has opposing parts that are pre-tensioned against each other, ensuring a secure yet comfortable fit of the shoe on the wearer's heel. The heel device is smaller than the size of the shoe into which it is incorporated to enhance the pre-tensioning effect of the opposing parts.

[0008] Document US 2004 / 0049945A1 concerns footwear with an upper that is separated from the sole at least on a portion of one side of the foot, allowing a foot to enter the footwear laterally through a side opening. The foot may be partially held by an elastic foot retainer that extends over the top of the foot. A heel retainer may also be provided near the heel area, the heel retainer working in conjunction with the elastic foot retainer to prevent the foot from slipping out of the opening while walking.

[0009] Document US 2005 / 0126042A1 relates to a shoe comprising a midsole, an outsole, an upper, a closure system, and a sole stiffening element. The midsole has a midsole base and a midsole top. The outsole consists of a forefoot area and a heel area. The upper extends upward from the midsole. The closure system is designed to allow movement between a tensioned and a released state. The sole stiffening element has a connecting section, a medial wing section, and a lateral wing section. The medial and lateral wing sections are positioned such that at least a portion of a straight line segment extending from the medial distal tip section to the lateral distal tip section is distributed over at least a portion of the upper surface of the midsole.

[0010] Document US 6,401,366 B2 describes footwear whose upper is attached to a longitudinal sole by a frame that preferably includes a stabilizing band extending between the axially decoupled heel and the opposing forefoot portions of the sole. The band has a central section that extends over the heel and forefoot portions of the sole and is adjacent to an upper, allowing the forefoot and heel portions of the sole to pivot axially about a longitudinal axis parallel to and above the longitudinal axis of the heel and forefoot portions, while resisting deflection in a direction perpendicular to the longitudinal extension of the sole. This supports the foot along its entire longitudinal extension, while allowing the footwear to adapt to the axial movements of an athlete's foot during running.

[0011] However, existing insoles and sports shoes do not reflect the specific needs of young athletes' feet regarding stability, shape, and support, which are discussed, for example, in the state-of-the-art document "Foot and Ankle Surgery Vol. 14 (2008) pp. 180-189." These specific needs include greater volume to allow for more movement and growth, as well as less cushioning, since the impacts experienced during training are significantly lower than in adults.

[0012] The object underlying the present invention is therefore to improve the soles of sports shoes, especially for young athletes, so that the disadvantages of the prior art outlined above are at least partially overcome. 3. Summary of the invention

[0013] The problem mentioned above is at least partially solved by the subject matter of the independent claims. The dependent claims define exemplary embodiments of the invention.

[0014] In one embodiment, the present invention provides a sole, in particular a sole for a sports shoe for a young athlete. The sole comprises a sole body comprising a first material. The sole body extends at least into a heel section and a midfoot section, the sole further comprising a substantially U-shaped stabilizing element comprising a second material that is stiffer than the first material. The said stabilizing element is arranged below the heel section and / or below the midfoot section of the sole body and is adapted to extend along the medial and lateral sides of a calcaneus of a wearer of a shoe comprising the sole.Additionally, the stabilizing element is designed to exert a pinching force at least against the calcaneus of a wearer of a shoe encompassing the sole, and wherein the stabilizing element comprises a lateral and a medial arm extending upwards and backwards from a lower section of the stabilizing element located below the heel section and / or below the midfoot section.

[0015] The claimed invention therefore provides a sole for a sports shoe that is specifically tailored to the needs of a young athlete by including a stabilizing element optimized for the anatomy and biomechanics of children's feet during their development. Unlike a conventional heel counter in sports shoes, this stabilizing element allows for growth and more appropriate support of a young athlete's foot. This support is achieved by encompassing the calcaneus (heel bone) of a child's foot, which undergoes only minor changes during growth compared to the rest of the foot. The stabilizing element can also be referred to as a bridging ligament or bridge brace.

[0016] In some embodiments of the present invention, the stabilizing element comprises a lateral and a medial arm extending upward and backward from a lower section of the stabilizing element, which is located below the heel section and / or below the midfoot section. The lateral and / or medial arm can extend upward and backward at an angle between 10° and 90°, preferably between 20° and 80°, and most preferably between 30° and 70°, relative to a base surface of the sole body. The different angles can allow adjustments in the height of the stabilization of the sports shoe, e.g., depending on the specific area for which the shoe is intended.

[0017] In some embodiments of the present invention, the stabilizing element is designed to exert a pinching force at least against the heel bone of the wearer of a shoe comprising the sole. Furthermore, the stabilizing element can have at least one contact surface suitable for pressing against a lateral and / or medial side of an upper part of a shoe comprising the sole.

[0018] This embodiment of the present invention makes it possible to apply a pinching force to an area of ​​the foot that generally exhibits relatively little growth and development compared to the rest of a young athlete's foot. Therefore, in this embodiment, the stabilization can still be comfortable and tailored to the individual foot, even though the size and shape of the foot may change slightly during growth. To generate such a pinching force, the medial and / or lateral arm can be pre-tensioned inwards. Alternatively or additionally, the medial and / or lateral arm can be curved inwards.

[0019] In some embodiments, the lower section of the stabilizing element has a longitudinal extension of less than 30%, preferably less than 25%, and even more preferably less than 20% of the sole length. The sole body may have a top surface with a contact area for the foot that is essentially flat. A flat midfoot engagement between the foot and the top surface of the sole, without arch support, has proven particularly advantageous for young athletes.

[0020] Furthermore, the stabilizing element can be positioned to fit into a recess or indentation in the sole, ensuring that no outer surface of the stabilizing element protrudes from the outer surface of the sole when installed. The stabilizing element can be flush with the sole. This arrangement improves the connection between the sole and the stabilizing element due to the mechanical interlock created by the tight fit of the parts. Additionally, this arrangement ensures that the shoe maintains a flat sole, which is essential for the wearer's balance and stability.Additionally, the lateral and medial arms of the stabilizing element can fit into recesses or indentations in the side of the sole, so that, at least for the most part, the outer surfaces of the arms do not protrude outwards from the sides of the sole when mounted. This arrangement allows for a reduction in the medial and lateral width of the sole.

[0021] In some embodiments, the lateral and / or medial arm of the stabilizing element each has a width of less than 30%, preferably less than 25%, and even more preferably less than 20% of the sole length. Such dimensions have been found to represent a reasonable compromise between the need to ensure stability and the need for unimpeded movement of the foot during a gait cycle.

[0022] The first material of the sole can be ethylene-vinyl acetate, EVA, rubber, or a combination thereof. Additionally or alternatively, the second material of the stabilizing element can be a thermoplastic material, in particular thermoplastic polyurethane, TPU, or rubber. Such materials can provide the necessary stability without compromising the other functions of a sole, such as cushioning and traction. The stabilizing element can be formed using conventional molding methods or additive manufacturing.

[0023] In another respect, the present invention relates to a sports shoe for a young athlete, which has a sole according to one of the embodiments mentioned above. In one aspect of this shoe, at least part of the stabilizing element can be attached to the upper, e.g. from the outside. 4. Brief description of the characters

These figures show: Fig. 1a an embodiment which schematically represents a sole body and a separate stabilizing element before they are joined together; Fig. 1b the embodiment of Fig. 1a, which schematically depicts the sole body and the stabilizing element after assembly; Fig. 2a an exploded view of a further embodiment comprising a sole body, a stabilizing element and an additional outsole; Fig. 2b the further embodiment in the assembled state in lateral side view; Fig. 2c the further embodiment in the assembled state in a view from below; Fig. 3 an illustration of a sports shoe in a view from below, a lateral and medial side view; Fig. 4a a second further embodiment which schematically shows a sole body and a separate two-part stabilizing element before they are joined together; Fig. 4b the second further embodiment in a medial side view; and Fig. 4c the second further embodiment in a top view. 5. Detailed description of some exemplary embodiments

[0025] Exemplary embodiments of the present invention are described below with reference to a sole, in particular a sole for a sports shoe for a young athlete. While specific combinations of features relating to the exemplary embodiments of the present invention are described below, it should be understood that the disclosure is not limited to such embodiments. In particular, not all features need to be present to realize the invention, and the embodiments can be modified by combining certain features of one embodiment with one or more features of another embodiment.

[0026] The Fig. 1a and Fig. Figure 1b shows a representation of parts of a sole, specifically a sole for a sports shoe for a young athlete. The sole comprises a sole body 110, which can extend into a heel section, a midfoot section, and a forefoot section. In this way, the illustrated design can provide cushioning for the entire foot of a young athlete. The sole body 110 can also extend vertically at the edges of the forefoot section to provide additional cushioning for the toes or to avoid the need for a toe cover or toe lip covering the front part of the shoe to ensure abrasion resistance. To ensure adequate flexibility in the desired areas of the sports shoe to which the sole comprises, the sole body 110 can have a height variation at its edges in the forefoot and / or midfoot sections.

[0027] The sole further comprises a substantially U-shaped stabilizing element 120, which includes a second material that is stiffer than the first material of the sole body 110. In one embodiment of the present invention, which may be particularly suitable for young children, the stabilizing element 120 may be rubber and the sole body 110 may be expanded EVA. This results in sufficient flexibility in the forefoot area, which is particularly important for young children who, compared to adults, often stand on their toes when walking or running. In another embodiment, the stabilizing element 120 may be TPU and the sole body 110 may be a rubber / EVA combination, which offers stiffer materials and may therefore be suitable for older children who are heavier and can exert greater forces on the athletic shoe.

[0028] While in Fig. 1a To illustrate, the sole body 110 and the stabilizing element 120 are shown separately. Fig. 1b Both components are joined together, which can be achieved by gluing, thermal bonding, or any other suitable technique. The recess or indentation 111 of the sole body 110 allows for a precise fit of the stabilizing element 120 to the sole body 110, whereby the lateral arm 121, the medial arm 122, and the lower section 123 of the stabilizing element 120 can be flush with the sole body 110. This results, on the one hand, in a smooth outer surface of the final sports shoe, which includes the sole, and avoids unnecessary protrusions that could pose a potential source of injury, especially during training. On the other hand, the indentations 111 of the present embodiment can also create an improved connection between the two materials with different degrees of stiffness.It should be noted that in another version the connection of the two parts may also have a structured pattern, e.g. ribs on the sole body 110 and corresponding indentations on the stabilizing element 120 or vice versa, to ensure a flush fit.

[0029] The lateral 121 and medial 122 arms of the stabilizing element 120 can extend upwards and backwards at an angle 124, which can be predefined during the sole manufacturing process. The specific angle 124, as well as the positioning of the stabilizing element 120 beneath the sole body 110, allows the sole to be adapted to a range of applications and several different activity levels. For example, in a design requiring greater support for the feet of a young athlete, the predefined angle 124 can be larger, even up to 90°, and the positioning beneath the sole body 110 can be further back in the shoe. In this way, the stabilizing element 120 can better support the heel bone and / or ankle of the wearer.In another design where less support is sufficient, the angle 124 can be smaller and the stabilizing element 120 can be positioned closer to or even in the midfoot area below the sole body 110.

[0030] Furthermore, this can be in Fig. 1a and Fig. The stabilizing element 120 shown in Figure 1b is provided with at least one contact surface 125, which is configured to press against a lateral and / or medial side of an upper part of a shoe that includes the sole. The at least one contact surface 125 may have a contact area larger than that of the rest of the medial 122 and / or lateral 121 arm in order to distribute the forces exerted by the stabilizing element over at least the calcaneus of a wearer and thus avoid possible discomfort.

[0031] In some embodiments, the width of the stabilizing element 120, which can be defined as the distance between the medial 122 and the lateral 121 arm, can be greater in the area below the sole body 110 than the estimated width of the foot of an average wearer. The resulting wide base of a sports shoe with this sole design can offer greater stability while simultaneously allowing unimpeded lateral foot growth.

[0032] The Fig. Figures 2a-2c show a further illustration of parts of a sole according to an embodiment of the present invention. The illustrations in the Fig. The sole shown in 2a - 2c comprises a sole body 210, a stabilizing element 220 and a running sole 230. Fig. 2a The various components are shown in an exploded view, where in Fig. 2b and Fig. Figure 2c shows the composite embodiment. The outsole 230 comprises a textured running surface that provides traction on the ground. Furthermore, the outsole 230 can have an entire structure 233 in its inner part, extending along the sole, thereby reducing the overall weight of the sole and maintaining the flexibility of the composite sole due to a selectively reduced amount of material in the outsole 230. The flexibility of the outsole 230, which is particularly important in the forefoot area of ​​a young athlete's sports shoe, can be further enhanced by a second type of indentation 232 on the parts of the outsole below the metatarsophalangeal joint of the wearer of the shoe, which includes the outsole 230. In this way, the indentations 232 in these areas can cause the sole and upper to flex when the foot is bent, conforming to the anatomical shape of the foot.The outsole 230 further comprises a protective component 231 which, in the assembled sole, covers the portion of the stabilizing element 220 that would otherwise be in direct contact with the ground. This prevents the stabilizing element 220 from eroding more than the outsole 230. This protective component 231, which may be rubber or another suitable material, can also be applied directly to the stabilizing element 220 in another embodiment (not shown).

[0033] Furthermore, this can be in Fig. 2a and Fig. The stabilizing element 220 shown in Figure 2b shall be provided with at least one contact surface 225 which is suitable for pressing against a lateral and / or a medial side of an upper part of a shoe which includes the stabilizing element 220. Fig. The lateral arm 221 and / or medial arm 222 of the stabilizing element 220, as shown in Figure 2a, can be adjusted to exert a pinching force at least against the calcaneus of a wearer of a shoe that encompasses the sole. For this purpose, the medial arm 222 and / or the lateral arm 221 can be pre-tensioned inwards. Additionally or alternatively, the medial arm 222 and / or the lateral arm 221 can be bent inwards. By increasing / decreasing the degree of curvature of the medial 222 and / or the lateral 221 arm, the magnitude of the pinching force exerted at least on the calcaneus of a wearer can be adapted to the specific area for which the shoe with the stabilizing element 220 is intended. Furthermore, the Fig. The stabilizing element 220 shown in Figure 2b has ribs 226 on its outer surface, which provide additional stability and reduce any potential twisting and bending of the stabilizing element 220 in undesirable directions. The ribs 226 can be produced by cutting out a portion of the material of the stabilizing element 220. This reduces the overall weight of the sports shoe, which benefits performance and simultaneously lowers manufacturing costs.

[0034] Fig. Figure 3 shows a shoe 300, in particular a sports shoe for a young athlete, comprising a sole according to one of the embodiments mentioned above and an upper 340. The stabilizing element 320 of the sports shoe 300 extends upwards and backwards at a predefined angle similar to the angle 124 of Fig. 1b and comprises at least one contact surface 325. The contact surface(s) 325 is (are) connected to the upper part 340 by gluing, thermal bonding, or another suitable technique. A pinching force generated by the inwardly pre-tensioned at least one lateral 321 and / or medial 322 arm can press against a corresponding lateral and / or medial side of the upper part 340, which presses at least against the calcaneus of a wearer of the shoe 300. In the illustrated embodiment of the sports shoe 300 made of Fig. In the third embodiment, the stabilizing element 320 is completely connected to the upper part 340 from the outside. In this way, the upper part 340 can provide sufficient cushioning to ensure comfortable wear for the wearer of the shoe 300. In another embodiment, the medial arm 322 and / or the lateral arm 321 of the stabilizing element 320 can extend further upwards to be in direct contact with the foot and / or ankle of the wearer (not shown). In this embodiment, the at least one contact surface 325 of the medial 322 and / or the lateral 321 arm can be provided with additional padding.

[0035] Similar to the outsole 230 made of Fig. 2c The sports shoe 300 also includes a sole 330 having indentations 332 to ensure the flexion of the assembled sports shoe 300, including the upper 340, at the desired points during walking or running. This effect can be further enhanced by height differences at the edges of the sole body 310. It is known that inappropriate flexion of a shoe, e.g., between the midfoot and the hindfoot instead of at the level of the metatarsophalangeal joint, can lead to stress on the foot, particularly the midfoot, which can be avoided in the present embodiment.

[0036] In the Fig. Figures 4a-4c illustrate an embodiment of the present invention comprising a sole body 410 and a two-part stabilizing element 420. The two-part stabilizing element 420 can be formed from two halves—one corresponding to the lateral arm 421 and the lateral half of the lower section 423 of a one-piece stabilizing element 120, 220, 320, and the other corresponding to the medial arm 422 and the medial half of the lower section 423 of the one-piece stabilizing element 120, 220, 320. The two-part stabilizing element 420 can be formed as two symmetrical halves, as shown in Figures 4a-4c. Fig. Figures 4a-4c illustrate the following configurations. Both halves can comprise a contact surface 425. In another embodiment, each part of the two-part stabilizing element 420 can be manufactured separately, according to the specific needs of the lateral and / or medial side of the support's foot. This can result in two halves with different and asymmetrical shapes, with each lower section 423 also having a different shape and length.

[0037] The recess or depression 411 on at least one side of the sole body 410 allows at least one lateral 421 and / or medial 422 arm of the two-part stabilizing element 420 to be arranged with a tight fit on the sole body 410. Furthermore, the recess or depression 411 on at least one side of the sole body 410 allows at least one lateral 421 and / or medial 422 arm of the two-part stabilizing element 420 to be arranged with a tight fit on the sole body 410. Fig. Figures 4a-4c show that the sole body 410 has an insert 412 on the underside of one or both recesses 411. The lower sections 423 of the lateral 421 and / or medial 422 arm of the two-part stabilizing element 420 can be adapted to fit flush into the at least one insert 412. In some embodiments, the inserts 412 can be connected within the sole body 410, and the lower sections 423 can include connecting means (not shown). The lower sections 423 can meet at a center point inside the sole body 410. The connecting means can be adapted so that the two bottom parts 423 can be fastened to each other within the sole body 410. Alternatively, the two parts of the two-part stabilizing element 420 can be joined together on a lateral side of the shoe sole or on a medial side of the shoe sole.In another embodiment, the recesses 411 of the medial and lateral sides of the sole body 410 can have separate slots 412 into which each of the lower sections 423 can separately snap into or fit.

[0038] In another embodiment (not shown), it is possible that the sole body 410 does not have any inserts 412 and the bottom parts 423 of the two-part stabilizing element 420 can be arranged similarly to the one in Fig. 1 and Fig. The two illustrated one-piece stabilizing elements 120, 220 are attached directly to the sole body 410 from the outside.

[0039] It is understandable that, unlike those in Fig.In the embodiments shown in Figures 1-4, the stabilizing elements 120, 220, 320, and 420 need not consist of only one or two parts. In some embodiments (not shown), the stabilizing element can comprise more than two parts, which can then be joined together during manufacturing. Additionally or alternatively, all or part of the stabilizing element 120, 220, 320, or 420 can be interchangeable for the end user. In other words, the wearer of the shoe 300 can specifically select a predefined level of support by exchanging one stabilizing element 120, 220, 320, or 420 for another that provides a higher or lower level of stability. This feature makes it possible to use the same sports shoe 300 with different levels of support for a wide variety of different applications.The different levels of stability can be indicated by a simple color coding, numbering or other systematic marking method on the stabilizing element 120, 220, 320, 420.

[0040] Furthermore, the medial 122, 222, 322, 422 and the lateral 121, 221, 321, 421 arms of the stabilizing element 120, 220, 320, 420 can be individually combined with a lower part 123, 223, 323, 423 or individually adjusted. In this way, the degree of stability on the lateral and medial sides could be changed separately, which would make it possible to specifically treat foot deformities such as overpronation and supination.

[0041] The connection between an interchangeable stabilizing element 120, 220, 320, 420 or parts thereof to each other and / or to the sole body 110, 210, 310, 410 can be made using hook and loop fasteners, a mechanical locking mechanism or another suitable connection technique (not shown in the figures).
