Changes of Foot Measurements Accompanied with Shoes-heel Height

Abstract

Right foot replicas of 10 male and 10 female Japanese adults were compared to clarify the foot sizes and shapes depending on the shoes-heel heights : 0 and 25 mm for males, and 0, 25, 45, 65 and 85 mm for females. The results were as follows in the case that the heel height difference was over 45 mm : a) foot width was shorter in case of higher heel height, b) there was a reversal relation between the dorsal and plantar surface lengths on the foot axis, that is, the former was a decrease and the latter was an increase, c) the medial part of ball-joint girth divided from the foot axis plane became longer and the lateral part one became shorter in accordance with the heel height increase, but the total ball-joint girth remained unchanged.
