鞋子设计知识（Shoes design knowledge） Factors affecting the comfort of the footwear products in five major categories: last design, pattern design, bottom part design, material selection and process design. A shoe last design, influence of comfort This design is based on the data of each part of the foot as the foundation, from the perspective of footwear design, which belongs to the first. This type of design will directly affect the appearance and comfortable shoes. 1. feet have four bows, namely the front, the back, the horizontal bow, the inside and outside the longitudinal bow. Feet in the course of movement, the four bow play the role of spring, slow down the ground reaction force. If the sole excessive convexity last design, with the last long wear shoes to do, will lead to the front transverse arch ligament damage, loss of elasticity, the subsidence, followed by cross bow, longitudinal arch collapsed, forming flat feet. The flat foot is easy to cause the patient to ache in the long time movement and stands. In the design of palm crown, to the foot of man as the basis, before and after the rocker design. The rocker, foot for natural warp as the basis, the former adult rocker highly control in general 15-18 ah, too high, will cause the forefoot excessive convexity. After crossing the higher forefoot convexity is small, before the rocker is smaller, so as to ensure the forefoot area, the wearer can not fall down.
