Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a stable support sole. Background Technology

[0002] Existing shoe soles, especially those for athletic shoes, generally consist of a midsole and an outsole. The midsole typically uses a relatively soft material (such as EVA) to ensure the sole's elasticity, cushioning performance, and soft comfort.

[0003] When the foot lands normally, the heel of the shoe sole hits the ground first, then transitions forward to the forefoot. When the heel of the shoe sole hits the ground first, it bears most of the pressure. If the midsole is too soft, after prolonged use, the inner side of the shoe sole may deform significantly, easily causing collapse and deformation, resulting in relatively poor support and stability.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0005] The purpose of this invention is to provide a stable support sole with relatively good support stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stable support sole includes an outsole and a midsole bonded to the outsole. A support plate is embedded within the midsole. The support plate has a higher hardness than the outsole, and the outsole has a higher hardness than the midsole. The support plate includes a first support segment and a second support segment integrally connected in sequence. The first support segment corresponds to the forefoot of the human foot, and the second support segment corresponds to the arch and heel. The second support segment extends out of the midsole from both sides. The support plate also includes a first support piece integrally connected to the inner side of the second support segment. The support pieces are arranged vertically, with the first support piece extending from the front end of the second support segment to the rear end of the second support segment.

[0010] As an improvement of this utility model, the midsole is designated as the forefoot portion corresponding to the position of the forefoot, the midsole is designated as the arch portion corresponding to the position of the arch, and the midsole is designated as the heel portion corresponding to the position of the heel. The rear end of the outsole has a third bifurcated opening groove that penetrates the outsole and extends to the arch. The opening of the third bifurcated opening groove is relatively close to the inner side of the outsole. The bottom of the midsole has a first groove corresponding to the third bifurcated opening groove.

[0011] As an improvement of this utility model, the bottom of the outsole is provided with a hollow groove, one end of the hollow groove is located at the position corresponding to the forefoot, the other end of the hollow groove is located at the position corresponding to the inner side of the arch, and the hollow groove runs through the outsole from top to bottom.

Detailed Implementation

[0018] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0020] like Figures 1-5 As shown, this embodiment provides a stable support sole, including an outsole 10 and a midsole 20 composited on the outsole 10. The midsole 20 is the forefoot part corresponding to the position of the forefoot of the human foot, the arch part corresponding to the position of the arch of the human foot, and the heel part corresponding to the position of the heel of the human foot.

[0021] For ease of description, the vertical direction of the sole is described as when the sole is placed normally on a horizontal surface. The side of the soles of the two shoes in the same pair facing each other is the inner side of the shoe, and the corresponding side is the outer side of the shoe. The side facing the toe is the front side, and the corresponding side is the back side.

[0022] A support plate 21 is embedded inside the midsole 20. The hardness of the support plate 21 is greater than that of the outsole 10, which in turn is harder than the midsole 20. The support plate 21 includes a first support segment 22 and a second support segment 23 that are integrally connected in sequence. The first support segment 22 corresponds to the forefoot of the human foot, and the second support segment 23 corresponds to the arch and heel of the human foot. In other words, the first support segment 22 and the second support segment 23 are a single unit without any clear division. The segments transition smoothly. The support plate 21 is divided into two segments only for ease of explanation. The two sides of the second support segment 23 extend out of the shoe... The midsole 20 and support plate 21 also include a first support piece 24 integrally connected to the inner side of the second support section 23. The first support piece 24 is vertically arranged and extends from the front end of the second support section 23 to the rear end of the second support section 23. The height of the first support piece 24 gradually increases and then gradually decreases from one end near the front side of the midsole 20 to the other end. A first embedding groove 25 is provided on the inner side of the midsole 20 for the first support piece 24 to be embedded. The first support piece 24 is embedded in the first embedding groove 25. The first embedding groove 25 cannot extend to the upper surface of the midsole 20. On the inner side of the outsole 10, corresponding to the position above the first support piece 24, a second support piece 26 is integrally connected. The second support piece 26 is vertically arranged, and the first support piece 24 is located above the second support piece 26. A second embedding groove 27 is provided on the inner side of the midsole 20 for the second support piece 26 to be embedded in. The second support piece 26 is embedded in the second embedding groove 27, which does not extend upwards to the first embedding groove 25. The first support piece 24 provides support and wrapping to the inner side of the midsole 20 at the position corresponding to the position above the first support piece 24. The inner side of the midsole 20 is wrapped and supported at the corresponding positions between the first support plate 24 and the second support plate 26. The position of the inner side of the midsole 20 above the first support plate 24 is the first layer, the position of the first support plate 24 is the second layer, the position of the inner side of the midsole 20 between the first support plate 24 and the second support plate 26 is the third layer, and the position of the second support plate 26 is the fourth layer. The first support plate 24 and the second support plate 26 work together to form a multi-layer support, which avoids excessive deformation when the inner side of the midsole 20 hits the ground first, and the support stability is relatively good.

[0023] The height of the second support piece 26 gradually increases from one end near the front of the midsole 20 to the other end, thus setting the second support piece 26 into a triangular structure, which improves the support performance of the second support piece 26.

[0024] The first support segment 22 has a first bifurcated opening groove 28 at the end away from the second support segment 23, and the first bifurcated opening groove 28 extends vertically through the first support segment 22. The second support segment 23 has a second bifurcated opening groove 29 at the end away from the first support segment 22, and the second bifurcated opening groove 29 extends vertically through the second support segment 23. By setting the first bifurcated opening groove 28 and the second bifurcated opening groove 29, a lateral shock absorption effect can be achieved.

[0025] The upper surface of the support plate 21 has a first reinforcing rib 30 and a second reinforcing rib 36 protruding upwards. In this embodiment, both the first reinforcing rib 30 and the second reinforcing rib 36 are arc-shaped ribs. The first reinforcing rib 30 and the second reinforcing rib 36 are arranged symmetrically along the center line of the width direction of the shoe midsole 20. The first reinforcing rib 30 and the second reinforcing rib 36 are arranged along the length direction of the shoe midsole 20. The distance between the first reinforcing rib 30 and the second reinforcing rib 36 gradually decreases and then gradually increases from one end to the other. By setting the first reinforcing rib 30 and the second reinforcing rib 36, it helps to increase the rigidity of the support plate 21, and at the same time improves the anti-torsion and mid-waist stability.

[0026] The second support section 24 has multiple first hollow holes 31 spaced apart along the length of the shoe midsole 20 at positions corresponding to the first reinforcing rib 30 and the second reinforcing rib 36. The second support section 24 also has multiple second hollow holes 32 spaced apart along the length of the shoe midsole 20 at positions corresponding to the side of the first reinforcing rib 30 away from the second reinforcing rib 36. The second support section 24 also has multiple fourth hollow holes 37 spaced apart along the length of the shoe midsole 20 at positions corresponding to the side of the second reinforcing rib 36 away from the first reinforcing rib 30. This arrangement helps to reduce the weight of the support plate 21.

[0027] The rear end of the outsole 10 is provided with a third bifurcated opening groove 33, which runs vertically through the outsole 10 and extends to the arch of the foot. The opening of the third bifurcated opening groove 33 is close to the inner side of the outsole 10 relative to the center line of the width direction of the midsole 20. The bottom of the midsole 10 is provided with a first groove 38 corresponding to the third bifurcated opening groove 33. This design can not only reduce the weight of the outsole 10 and the midsole 20, but also play a lateral cushioning role.

[0028] The bottom of the outsole 10 has a hollowed-out groove 34. One end of the hollowed-out groove 34 is located at the position corresponding to the forefoot, and the other end of the hollowed-out groove 34 is located at the position corresponding to the inner side of the arch of the shoe. The hollowed-out groove 34 runs through the outsole 10 from top to bottom. The bottom of the midsole 20 has a second groove 39 corresponding to the hollowed-out groove 35. This design can not only reduce the weight of the outsole 10 and the midsole 20, but also improve the appearance of the sole.

[0029] The outsole 10 has at least one third hollow hole 35 at the position corresponding to the forefoot. The bottom of the midsole 20 is provided with a third groove 40 corresponding to each third hollow hole 35. In this embodiment, there are three third hollow holes 35, and each third hollow hole 35 is arranged at intervals along the width direction of the midsole 20. This arrangement can reduce the weight of the outsole 10 and the midsole 20.

[0030] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
