Abstract: To build a mathematic model for predicting the average pressure caused by socks, we analyzed the relationship between the average pressure, the potential energy of the fabrics and the shape of the section of lower leg. We also described the theoretical analysis of the pressure, and found a model which could predict the average pressure caused by socks, by using SPSS’ nonlinear regression analysis to reveal how those three factors are related to each other, at last. This model will simplify the calculation method, and provide a thearetic foundation for the accurate prediction of the pressure.

Key words: hose, pressure, elastic material, elastic potential energy, energy conservation
