A kind of sole of children's shoes based on biomechanics

Abstract

The invention discloses a biomechanics-based children shoe sole. The shoe sole is shaped like a fan with the wide front portion and the narrow rear portion, and comprises a landing layer, a pressure layer, a protective layer and a foot arch supporting layer. The hardness of the foot arch portion and the hardness of the heel portion of the landing layer are greater than that of the half sole portion. The hardness of the portion from the third phalanx to the fifth phalanx, the portion of the first phalanx and the portion of the inner side of the heel, the hardness of the portion between the first phalanx and the second phalanx, the portion between the fourth phalanx to the fifth phalanx and the portion of the outer side of the heel, the hardness of the portion between the second phalanx and the third phalanx and the hardness of other portions of the pressure layer are reduced gradually. The protective layer is made of slowly recovering materials. The shape of the foot arch supporting layer is the same with the shape of the foot arch of a child. The thickness of the foot arch supporting layer is decreased gradually from the inner side to the outer side in the transverse arch direction of the foot arch, and is decreased gradually from the middle to the two sides in the inner side longitudinal arch direction and the outer side longitudinal arch direction of the foot arch. The biomechanics-based children shoe sole has the advantages of meeting the children biomechanics characteristic, being high in comfort level and impact resistance, and the like.

Description

technical field [0001] The invention relates to the field of soles of children's shoes, in particular to children's shoes that are suitable for the development of children's feet by setting appropriate hardness at corresponding bone positions according to children's biomechanics. Background technique [0002] The arches of the foot include the medial longitudinal arch, lateral longitudinal arch, and transverse arch (eg figure 1 As shown), its main function is to disperse the gravity from the ankle joint forward through the talus to the head of the metatarsal bone, and transmit it backward to the calcaneus, so as to ensure the stability of the plantar support when standing upright. When the body jumps or falls from a height to the ground, the elasticity of the arch of the foot plays an important role in cushioning the shock. [0003] At present, the research and development and production of children's shoes are basically implemented by imitating the technology of adult shoe...

AI Technical Summary

Problems solved by technology

However, children at this stage generally have physiological flat feet. If the soles are only equipped with simple arch supports, the simple arch supports will cause the stretching space of the arch to be reduced, and the arch muscles that are just in development will be strengthened. Without the necessary exercise, the stability of the joints of the foot will not be enhanced, and it will be inevitable to become a real flat foot in the long run

[0004] In addition, the sole hardness of current shoes is mostly the same. Even if there are shoes with different sole hardness, they are designed according to the characteristics of adults' feet. For manufacturers of research, design and production of children's shoes, their attention is still Only limited to changes in the style, color and shape of children's shoes, there is no biomechanical-based children's shoe sole designed specifically for the physiological and morphological characteristics of children's feet in the prior art

[0005] Moreover, the material used for the part of the soles of current children's shoes close to the skin is basically the same as that of adults' soles, generally cloth, leather, etc., because children's feet are very fragile, the material of the soles of children's shoes in the prior art Poor skin affinity, poor comfort, and cannot provide favorable cushioning, which is not conducive to the growth and development of children's feet

[0006] Studies have shown that children in my country generally have the problem of wearing improper shoes, foot discomfort, and foot deformities, to a large extent, are caused by the unreasonable design of the soles of children's shoes
