The top surface of the front end part of the wedge position embedded sheet is provided with an arched surface, and the top surface of the rear end part is provided with a concave arched surface.

The following detailed description is made with reference to the accompanying drawings.

As shown in figure 1, the bottom layer structure of the sports insole comprises a foot cup 1 formed by TPE and a rear supporting part 3 formed by TPU hard material, wherein a wedge bone position embedded sheet 2 is arranged on the outer side of the front end of the rear supporting part 3, the wedge bone position embedded sheet 2 is an elastic gasket, namely an elastic body, the hardness is 33-37N/mm²And the thickness is 3.5-6.0 mm. The wedge bone position embedded sheet 2 is strip-shaped. A strip-shaped wedge-bone-position insert mounting hole 31 is formed in the front portion of the outer side of the rear support portion 3, and the wedge-bone-position insert 2 is fixed in the wedge-bone-position insert mounting hole 31.

The thickness of the TPE formed foot cup is 1.8-2.5mm at the front end and 3.5-4.5mm at the rear end. A layer of high-density memory foam which is used for clinging to the bottom of the foot is fixed on the upper surface of the TPE formed foot cup.

Wherein, the part of the TPE-shaped foot cup corresponding to the sole of the foot of the human body is a plane part and is used for bearing the stress of the sole; the heel part of the human foot is a convex part slightly protruding towards the direction of the sole, the shape of the convex part is coincided with the heel bone of the rear sole, the heel bone is a whole hard bone, and a thick fat pad is arranged below the heel bone, so that the shock absorption effect is realized. The TPE material is superposed on the calcaneus part and is equivalent to a second layer fat pad of a human body, and the TPE material plays a role in double buffering and shock absorption during movement; the arch part corresponding to the foot arch of the human body is a transition part according to the arch position of the foot of the human body, the outer side is low and flat, and the inner side is high. Fascia and nerves are distributed at the bottom of the arch foot, the inner side of the arch foot is easy to fatigue or collapse, and if the sole is too low to support, the arch foot can collapse and the fascia on the sole is inflamed; if the support is too strong and high, the footstrike is painful. Arch TPE material such as spring loaded spring force is scaled to effectively support the arch properly. The rear supporting part is uniformly distributed on the basis of 1.5mm of TPU material, the front end of the rear supporting part reaches the position of the metatarsal bone position of a human body, the rear end of the rear supporting part reaches the rear edge of the TPE formed foot cup, the shape of the rear supporting part is matched and fixed with the corresponding position of the TPE formed foot cup, the TPU hard material is positioned at the bottom layer and combined with the upper TPE elastic material to achieve double stabilizing effect, and the calcaneus position can be uniformly positioned at a natural and comfortable position even under severe motion.

The rear supporting part is formed by TPU hard material.

In the application, the high-density foam is synthesized by artificial materials similar to sponge and is not purely natural. High density foam is referred to herein as slow rebound foam. TPE (Thermoplastic Elastomer) is a Thermoplastic Elastomer material, has the characteristics of high strength, high resilience and injection molding processing, and is environment-friendly, nontoxic and safe. TPU (thermoplastic polyurethanes) are known under the name thermoplastic polyurethane elastomer rubbers.

Referring to fig. 2, a wedge bone insert 2 is a strip for guiding stride, which has a front end and a rear end, i.e. a length of 40-60mm, a bottom surface and a top surface, a middle portion with a width smaller than that of the two ends and a width of 10-25mm is suitable, the width of the two ends is 20-30mm, and the optimal value is obtained according to the actual value and can be other values. The cuneiform position embedded sheet is an elastic gasket with the hardness of 33-37N/mm²And the thickness is 3.5-6.0 mm. The top surface of the front end part of the cuneiform bone position embedded sheet 2 is provided with an arched surface, and the top surface of the rear end part is provided with a concave arched surface.

The bottom structure of the sports insole of the utility model can be independently arranged and used.

The utility model discloses the substructure of motion shoe-pad can use jointly, all set up the inserted sheet cooperation in the calcaneus department of foot and metatarsal department promptly and use, add multiple hardness elasticity inserted sheet in metatarsal position, wedge position, calcaneus position, each inserted sheet accomplishes respective function, stiff calcaneus position inserted sheet impedance foot excessively pronates promptly, compare with the more soft wedge position inserted sheet guide of bone position inserted sheet strides, and metatarsal position inserted sheet is used for taking precautions against earthquakes, the shock that produces when the effective absorption foot landed vibrates. Finally, the tension is reduced, the foot is helped to perform natural rotation shaft movement, the calcaneus and the metatarsus which bear the pressure are in natural and comfortable positions, the walking is facilitated, and the requirements of modern people on comfort, health and higher standards are met.

The material in this application can be high density foam, is just like the synthetic of sponge-like artificial material, non-pure natural. High density foam is referred to herein as slow rebound foam. TPE (Thermoplastic Elastomer) is a Thermoplastic Elastomer material, has the characteristics of high strength, high resilience and injection molding processing, and is environment-friendly, nontoxic and safe. The material of the present application is the material used for the embodiment, for example, foam can be used, and the hardness change is realized through the setting of different densities. The specific material is selected according to the actual situation.

The above description is only an embodiment of the preferred embodiments of the present invention, and not intended to limit the scope of the claims of the present invention, so that all the structural equivalent changes made by the present specification and drawings are included in the scope of the present invention.
