Abstract: Firstly, through the investigation of the current sports socks market, the paper finds that the functional design of most sports socks is relatively weak, and it is difficult to meet the increasingly specialized wear requirements of consumers. Secondly, based on the analysis and discussion of the physiological structure of the bones, joints and muscles of the foot, the paper details the functional requirements of sport mechanics and heat-moisture comfort by combing with the sport physiology like foot movement gait, heat-moisture distribution, etc. Finally, the paper carried out an optimal design of the functional division of the sports socks based on the characteristics of the knitted fabric texture of the commonly used sports socks.

Key words: foot physiology; sports functional socks; heat-moisture comfort; socks design
