This application is through at the built-in special rigid structure material of shoe insole to obtain the running shoes sole that effectively improves the economy of running. Compared with the traditional running shoes, the purpose of the application is mainly to improve the running efficiency to the maximum extent.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a rigid component provided in an embodiment of the present application. The rigid part is a component for the sole, and can be divided into a half sole section 1 and a heel section 2 according to the position corresponding to the foot, the half sole section and the heel section are longitudinally connected to form a rigid plate-shaped structure which integrally covers the sole of the foot, namely the rigid part, and the surface shape of the rigid part is basically consistent with the shape of the sole of the foot. The rigid component has high rigidity and high toughness, the main preparation material can be carbon fiber (carbon fiber), glass fiber (glass fiber) or nylon and other high-rigidity and high-toughness materials, and the rigid component is preferably prepared by the carbon fiber and can be called a carbon sheet or a carbon plate.

Some embodiments of the present application use a thermoplastic carbon sheet prepared by a method comprising: the carbon plate sheet with the thickness of 1-2 mm is subjected to CNC cutting into small pieces (the currently adopted example is the thickness of 1.2 mm), then heating and prepressing are carried out, then the carbon plate sheet is put into a die to be subjected to secondary preheating and pressurization, and finally trimming and cleaning are carried out to finish the preparation. The rigidity performance test of the rigid part specifically comprises the following steps: static rigidity testing 5mm strain testing; the half sole stress is generally 0.3-0.5KN, the middle waist stress is 0.2-0.3KN, and the heel stress is 0.2-0.3 KN.

The rigid component is integrally of a spoon-shaped three-dimensional structure with a low front part and a high back part by taking a ground horizontal plane as a reference. The half sole section 1 is a region longitudinally extending from the position corresponding to the toes to the front end of the arch of foot with curvature, and the shape of the projection outline corresponds to the projection outline of the half sole of foot; the toe-bending device can be further divided into a corresponding toe area (part) and a corresponding metatarsal bone area, wherein the foremost end of the corresponding toe area is the foremost end of the rigid component, one side corresponding to the big toe is the inner side, and one side corresponding to the small toe is the outer side; the end corresponding to the metatarsal bone area corresponds to the front end of the arch of foot and has smaller width. The foremost line of the front palm section corresponding to the toe part can be a straight line or a curve (including a circular arc line or a bending line conforming to the outline of the toe). The fore-sole section extends in an arc shape longitudinally, and the curvatures of the corresponding toe area and the corresponding metatarsal area can be consistent or slightly different.

The heel section 2 extends from the corresponding heel to the front sole section 1, specifically extends to the front end of the arch, and comprises a corresponding heel area (part) and a corresponding arch area; the rearmost end of the corresponding heel area is the rearmost end of the rigid component, and the corresponding arch area is the connecting part of the heel section and the half sole section.

In some embodiments of the present application, the forefoot segment has an oblique angle in the lateral direction, and the heel segment may be horizontal or oblique in the lateral direction. Alternatively, in other embodiments, the forefoot section is laterally non-inclined and the heel section is laterally inclined. The working principle of the application is that according to the force application characteristic of foot transition during racing running, a rigid part (rigid part) with a certain radian fall shape is designed, and the transition benefit of running is improved.

For racing marathons players, the running gait is generally from the lateral side of the full sole or the lateral side of the half sole to the first landing, to a slight transition to the heel, and then to a rapid transition to the medial kick-off. Most high-level runners, during running, have a foot that lands on the outside and then transitions rapidly to the inside in the left-right direction.

The applicant has found that, in addition to the front-rear direction, a rapid transition in the form of an arc is required, and in the left-right direction, a rapid transition in the form of an arc drop is also required, which is mainly achieved by the transverse tilt drop stiffness of the rigid part according to the present application. The angle of inclination of the laterally inclined region of the forefoot segment and/or the heel segment, with respect to the ground, independently does not exceed 10 °, preferably is between 5 and 10 °, for example 6 and 9 °. In some shoe soles, the rigid member may be angled with a high inside and a low outside to promote rapid transition. In particular, the outer side of the foot of some runners is grounded first, and the outer side of the rigid member is lower, which can provide better cushioning; the angle of inclination of the rigid part can improve the transition effect from the outer side to the inner side; the inner side of the foot is the main stressed area, and the rigid part is higher at the inner side, so that the stability can be improved.

In some embodiments of the present application, the heel section is horizontal and the forefoot section has an oblique angle in the lateral direction; the left end and the right end of the transverse inclined part can have no fluctuation, namely, the transverse inclined part is in a smooth spoon shape or a design with gradient (such as a longitudinal gradient sectional transition till a heel section). Alternatively, in other embodiments, the heel section is horizontal and the forefoot section is at an oblique angle in the lateral direction; the left and right ends of the transverse inclined part are rounded, and the rounded shape can extend along a straight line or a curved line, for example, at least one WAVE (WAVE) shape or S shape.
