Footwear fitting and comfort is an important customer need which involves multiple factors. It includes both objective measurements and subjective perceptions, and can be influenced by shoe materials, weight and styles, foot shape, inside shoe climate, even colour and fashion. However, the influences of other design factors are still not clear. This research investigated the relationship between footwear design factors and footwear fitting and comfort. Two-level fractional factorial design analysis was used to evaluate the effects and find the vital factors. The results indicated that heel height has relatively significant influences on footwear comfort. High topline, low heel height, soft material, round toe, open toe, open heel and thin platform can provide better fitting and comfort.
