Abstract
Designers rely heavily on the past sales history of a particular shoe when attempting to make decisions regarding shoe characteristics of future shoes. Cushioning devices made of air, “super” gases, energy return rubber, and gel's have become popular. However, the question that needs to be asked is whether these devices are truly functional or whether they are primarily of aesthetic value. Shoe qualities such as cushioning, comfort, stability, shock absorption, and energy return play an important role during athletic activity. It is also known that the above mentioned characteristics have significant interactions with each other. Hence it is important to know the relevance of these interactions when designing shoes for a particular activity. The primary goal of this study was to investigate the interaction and relevance of shoe properties during running and walking. Four specially fabricated shoes were used in the study. The results indicate the following:
Heel cushioning and shock absorption play an important role in the overall cushioning of a midsole. Runners perceive shoe-heel cushioning somewhat differently from those who use shoes for walking. Heel cushioning during running seems to be influenced by shock absorption, stability and possibly rebound. Heel cushioning during walking seems to be influenced by shock absorption and possibly rebound. Hence a good running shoe can in most cases satisfy the biomechanical needs during walking.
