Typically, men's shoes use an insole or heel pad at the back half. Women's shoes are covered with a full insole. The insole has the function of keeping the insole clean and covering the unevenness of the insole to improve foot feel. Therefore, insoles should have good moisture absorption and drainage properties. In terms of workmanship, the insole should adhere flat to the inner sole without any hanging wrinkles.

Most of the raw materials for sports shoes are synthetic polymer materials (mostly polyester nylon mesh and non-woven synthetic leather, with rubber or rubber foam materials used as the sole), and some shoe uppers are made of genuine leather. Therefore, it is important to avoid contact with organic reagents and oil solutions, and it is also not advisable to wear them for a long time in high temperature environments. Generally, the temperature for wearing or washing should not exceed 45 degrees Celsius.
