Abstract
To quantify subjective perception of fit using objective measurements, 15 healthy male subjects were invited to participate in this study. Subjective fit ratings of shoes during standing and walking were measured using fit questionnaire with VAS scale. Pressure sensors and foot scanner were used to determine the shod-foot interface pressure and the dimensional differences. Regression was run and the capability of objective measurement to predict fit rating was determined. The R square increased from 30.7% (dimensional difference) and 25.5% (pressure sensors) to 62.6% by (dimensional difference and pressure sensors). Each of the objective measurements above has its own limitation in quantifying fit. However, when using both dimensional difference and pressure sensors, they were able to compensate the limitations and restrictions of each other, thereby increasing the power to predict subjective fit rating.
