In order to investigate the possibility to estimate the fitting comfort from physical measurements, relations between the fitting comfort of running shoes, parameters indicating differences between foot and last forms, and in-shoe pressures were examined. The subjects were 12 young adult male long distance runners. Running shoes made on the normal width last and widelast, made of the same materials and with the same outlook were used. The fitting comfort and the pressure sensation were evaluated by sensory evaluation. 3D forms of the right and left feet of the subjects were measured using a foot scanner. In-shoe pressures were measured with pressure sensors. A clear relation was observed between the pressure sensation at the ball, the ball heights difference, and the pressure at the ball, as well as between the pressure sensation at the heel and the heel breadth difference. When subjects were divided into two groups based on the running shoe size which they usually wear, those wearing smaller shoes preferred larger pressure sensation at the heel and toes, and those wearing larger shoes preferred smaller pressure sensation. These findings indicate the possibility to estimate the fitting comfort of running shoes from physical measurements of the foot and last.
