Abstract: Experiments designed dress shoes with different metatarsophalangeal girth and feet width. Eight subjects whose feet are healthy were recruited to try on these shoes. Subjective and objective evaluation was made on the comfort of the shoes, and the change rule of comfort was obtained. In terms of subjective evaluation,participates gave scores while wearing the testing shoes directly;whereas,objective experiments were conducted to collect the peak pressure and impulse of the forefoot through novel pedar-X insole system.The results showed that by subjective comfort evaluation method, the optimal difference range of metatarsophalangeal girth and feet width between foot and last was determined to be (3.6-5.2)mm and (6.3-8.7)mm, respectively.The peak pressure and impulse were basically consistent with subjective evaluation results, which could effectively distinguish comfort of different shoes. The combining subjective and objective evaluation results, the average difference of metatarsophalangeal girth and feet width were (4.45±0.49) mm and (7.29±0.72) mm, respectively.
