Fitting comfort is one of the most important factors when runners choose suitable running shoes. In order to assess fitting comfort from the foot and shoe (last) morphological factors, the relationship between fitting comfort of running shoes, foot forms and last forms were examined. Subjects were 31 student athletes. 16 running shoes (size : 250-285,width : normal and wide) were used for the experiment. The design and the material of shoes were the same. Each subject decided the best shoes and evaluated fitting comfort of his best shoes, one size larger shoes and one size smaller shoes by Visual Anglogue Scales at 6 locations of the foot. The 3D form of the foot and last were measured using a 3D foot scanner. The results of ANOVA indicated that the fitting comfort was significantly different between the 3 shoe conditions. The tightness was recognized at the location in the forefoot, and the looseness at all locations. The difference in the width between the foot and last was calculated for the ball and heel, and used as the indicator of the morphological fit. It was highly correlated with foot breadth (r=-0.874), foot circumference (r=-0.882) and heel breadth (r=-0.926). These results suggest the possibility to estimate the fitting comfort from the foot and last morphology, and that the fitting comfort is dependent on the habituation.
