Problems solved by technology

However, when strenuous exercise is required, traditional insoles are unsuitable and unsafe, and have the following disadvantages: First, the effects of shock absorption and foot protection are poor. 1. The impact force on the foot bones during exercise makes it difficult to protect the plantar bones, ankle joints and knee joints; 2. Poor anti-slip performance is not conducive to stretching and gripping the toes; 3. Traditional insoles have poor air permeability and are easy to breed bacteria , fungus, prone to foot problems such as athlete's foot; Fourth, traditional insoles do not have the effect of wrapping the feet, and cannot prevent joint displacement during strenuous exercise

Abstract

The invention discloses shoe pads having a protection effect during strenuous exercise. Each shoe pad comprises a shoe pad body, wherein the shoe pad body sequentially comprises a shoe pad half sole, a shoe pad middle-rise part and a shoe pad heel from the front end to the rear end, 2-5 rings of annular grooves are arranged at the upper side of the shoe pad half sole, and 2-5 horizontal wavy grooves are formed at the positions, corresponding to the toes of the human body, of the shoe pad half sole; 3-5 C-shaped grooves are formed in each of two sides of the shoe pad middle-rise part; a plant fiber arch supporting cushion plate is arranged at the lower side of the shoe pad middle-rise part; 80-150 small holes are distributed at the lower side of the shoe pad body, so that an elastic net-shaped structure is formed; the shoe pad body comprises a bamboo carbon fiber layer, a first PU polyurethane foam layer and a second PU polyurethane foam layer in the sequence from top to bottom, and a half sole cushioning pad and a heel cushioning pad are arranged at the lower side of the first PU polyurethane foam layer. The shoe pads having a protection effect during strenuous exercise provided by the invention have good damping and foot protecting effects and good slip resistance, can prevent the ankles from being injured, and are good in breathability.

Description

technical field [0001] The invention relates to an insole, in particular to a protective insole for strenuous exercise. Background technique [0002] Insoles are widely used daily necessities. According to their functions, insoles can be divided into health care insoles, functional insoles and conventional insoles. The structure of the traditional insole is sewn from multiple layers of cloth or pressed from multiple layers of leather. It has a certain degree of softness and cushioning and shock absorption, which basically meets the needs of ordinary walking shoes. However, when strenuous exercise is required, traditional insoles are unsuitable and unsafe, and have the following disadvantages: First, the effects of shock absorption and foot protection are poor. 1. The impact force on the foot bones during exercise makes it difficult to protect the plantar bones, ankle joints and knee joints; 2. Poor anti-slip performance is not conducive to stretching and gripping the toes; ...
