Abstract: The dynamic pressure distribution of elastic human body is critical for pressure comfort and optimal design of apparel products. This paper reports on an analytical study of the dynamic pressure based on top part of man’s socks, the dynamic pressure is divided into two parts, the first is pressure with pressure, and the second is pressure with walking. The pressure with time is set a period of 12 hours, after measuring pressure values of different periods and using ANSYS software, the tendency of pressure and displacement change with time at top part of man’s socks can be obtained. We divide the walking process into four phases, and analyze the variation rule of pressure and displacement change with movement. Meanwhile, lower leg cross section is divided into four equal regions according to angle, the area shrinkage mass with the period of dynamic can be calculated, respectively, all these solutions supply a theoretical reference for optimal design of the top part of men’s socks.
