US Patent 11176738 Method for calculating the comfort level of footwear

A method for measuring shoe comfort level is provided. A 3D polygonal model of a foot is constructed from an array of images taken from multiple angles of the foot and leg. Each vertex point is loaded with foot anthropometric sensitive characteristics information. A 3D model of a shoe's inner space is constructed with a scanning device having various opening modes. Each of shoe inner space vertex points is complimented by shoe data such as material type, rigidity, structure, vamp and shoelaces. The 3D polygonal foot model and the vertex inner shoe space model are fitted together and the comfort level for the foot is defined with the simulation of movement.
