Description

Insole and outsole structure of sports shoe

Technical Field

The invention belongs to the field of sports shoes, and particularly relates to a midsole and outsole structure of a sports shoe.

Background

At present, most of sole structures of mainstream common sports shoes are midsoles made of EVA (ethylene vinyl acetate) or other damping materials, and outsoles made of rubber. When people wear the sports shoes to do sports, the midsole material is required to have four functions of cushioning, supporting, extending, softness and easy curling. However, these characteristics are mutually contradictory in many scenarios: for example, when the sole falls to the ground, the midsole is required to be soft enough to absorb and share impact force, and meanwhile, the sole is required to have enough lateral support or the sole is required to turn outwards; when the sole starts to lift off, the insole is required to have enough longitudinal supporting force if the insole has quick response, and meanwhile, when the human sole bends and exerts force in the tarsal bones, the metatarsal bones to the phalanges in the lift off action, the insole is required to have transverse softness and heel. The mere use of one material and construction certainly compromises the performance of the athletic shoe.

The technical scheme adopted by the invention comprises a midsole support framework, a midsole stabilizing sheet and an outer wrapping layer; the insole supporting skeleton consists of a phalange supporting sheet, a metatarsus supporting sheet, an arch supporting sheet and a heel supporting sheet, the side walls of the insole supporting skeleton are provided with longitudinal supporting structures, and one side of the inner sole is provided with an installation clamping piece; the insole stabilizing sheet is a part similar to Arabic numeral '8', the part is provided with two mounting holes, the part is sleeved on mounting clamping pieces on the inner sides of the soles of the phalange supporting sheet, the metatarsus supporting sheet, the arch supporting sheet and the heel supporting sheet to play a role in connection and stabilization, and arch parts are arranged at positions between the phalange supporting sheet and the metatarsus supporting sheet, between the metatarsus supporting sheet and the arch supporting sheet and between the arch supporting sheet and the heel supporting sheet to play a role in deformation of soles in the process of bending and exerting force; the outer wrapping layer is a soft rubber part with a hollow structure, has dual functions of an outer sole and an inner sole, is divided into a split structure with side links at the outer bottom, is of a hollow cellular structure at the inner bottom, is inserted into the mounting groove in the outer wrapping layer together with an installed insole supporting framework and an insole stabilizing sheet, and is adhered to one side of the outer sole of the insole supporting framework by the outer sole structure of the wrapping layer.

Preferably, the midsole support frame is made of plastic, carbon fiber or other high-performance composite materials with hard and impact resistance, and the shape of the phalanges, the metatarsals, the arch and the heel of the foot of the human can be simulated respectively, and the four stressed parts of the sole of the foot of the human can be divided.

Preferably, the midsole stabilizing sheet is made of plastic, carbon fiber or other tough and elastic high-performance composite materials, and simulates the shape and the bending state of a plantar fascia, so that the midsole stabilizing sheet can be used for connecting four large stress parts and providing a certain movement space for the bending movement of the sole.

Preferably, the outer wrapping layer is made of rubber or other composite materials with certain elasticity and wear resistance, simulates the functions of human plantar muscles, wraps the midsole supporting framework and the midsole stabilizing sheet, and plays a role in relieving the mutual impact of the midsole supporting framework, insole supporting and outsole friction.
