midsole of a high-heeled shoe

Abstract

The invention relates to the technical field of production in the shoe industry, and discloses an insole of a high-heeled shoe. The insole comprises a shoe insole body which sequentially comprises a heel part, an arch flank part, a toe part and a front palm part from back to front. The portion, between the heel center of the heel part and a concave point on the front palm part, of the top face of the shoe insole body is a lower groove face. By means of the lower groove face, the top face of the outer side of the arch area of the shoe insole can completely contain muscle which is located on the bottom face of the outer side of the arch area of a human foot and protrudes downwards in the longitudinal direction when the shoe is put on, the muscle at the position is prevented from being extruded towards the shoe edge on the outer side of the shoe, the matching degree of the top face of the arch area of the shoe insole and the bottom face of the arch area of the human foot can be improved, the stress distribution of a sole can be more uniform, the comfortable sensation and beauty of a shoe wearer can be improved, the wearing life of the shoe can be guaranteed, health of the human foot can be protected, and the phenomena of foot aches and foot deformation can be avoided.

Description

technical field [0001] The invention relates to the technical field of shoe production, in particular to a midsole of high-heeled shoes. Background technique [0002] The midsole is the main component part in the shoe, which is installed on the sole as a shaped part so as to directly support the sole of the human body. Most of the midsoles of existing high-heeled shoes are horizontally tiled structures along the streamline of the soles, especially in the arch and waist of the midsoles, the characteristics of which are more obvious. Observation shows that the bottom surface of the arch area (that is, the area between the heel center of the heel and the concave point of the forefoot, including the lumbar fossa and the metatarsophalangeal) is not a flat surface structure, and there are obvious structures on the inner side of the arch area. The arch-shaped concave feature, but there is a longitudinal convex muscle feature distributed on the outside of the arch area, especially ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned problems of the midsole of the existing high-heeled shoes, the present invention provides a midsole of the high-heeled shoes, which can completely accommodate the top surface outside the arch area of ​​the midsole of the human body when wearing the shoes. The longitudinally convex muscles on the bottom prevent the muscles from being squeezed towards the outer edge of the shoe; on the other hand, the upper surface of the inner side of the arch area of ​​the midsole of the shoe is arched and convex to match the corresponding human foot The arch-shaped concave feature on the inner bottom surface of the arch area of ​​the foot achieves strong support for the inner bottom surface of the arch area, so that the height of the top surface of the arch area of ​​the midsole of the shoe can be matched with the bottom surface of the arch area of ​​the human foot, so that The distribution of force on the sole of the foot is more uniform, which not only improves the comfort and aesthetics of the wearer, ensures the wearing life of the shoe, but also protects the health of the human foot, avoiding foot soreness and deformation of the foot
