A-19 Designing of sock liner considered heel height variation in pumps

Abstract

Pump have been widely worn by ladies in various scenes. The most characteristic of pump is heel plugs with various height, it is very effective to make the ladies' style more beautiful. On the other hand, the specific structures make bad influences on shoe functions such as stability, cushioning, fitting and flexibility. In order to satisfy the above functions, this paper focuses on the sockliner designing. First, with increasing the heel position, foot geometry change is systematically measured by INFOOT systems. Based on the measurement results, sockliners are practically manufactured. Through walking motion analyses with sockliners manufactured, the effects are quantitatively evaluated. Therefore it was confirmed that the sockliner with the correct geometry could relax the foot pressure at MP area.
