The structure, specifications, and quality of socks

Socks are composed of three parts: the sock mouth, the sock tube, and the sock foot. The sock feet include the heel, sole, back, and toe of the sock. The function of the sock opening is to prevent the edge of the sock from falling off and tightly fitting onto the leg. There are five main parameters for socks: sock size, sole length, total length, mouth length, and heel height.
