Deformation of feet to be caused by wearing shoes was investigated with x-ray measurement on 118 feet of 59 young female subjects (in their 20's) and 100 feet of 50 middle-aged ones (in their 50's) . Respective differences (Δ) between bare and shoed feet regarding 18 somatometric measurement items were analyzed, which yielded the results as follows:
(1) The width group measurements of shoed feet were smaller than those of bare feet, and the antero portion measurements were bigger. Consequently it was clear that shoed feet were distinctly deformed at the antero-tibia and antero-fibula side portions.
(2) All shapes of frequency distribution of the differences (0) were not necessarily symmetrical around the mean values.
(3) This discrimination analysis, resulting correct discrimination over 83% on both young and middle-aged groups, proved that bare feet are different from shoed feet.
(4) Factor analysis on deformation caused by wearing shoes educed these portional factors : foot width, instep height, form of antero portion and form of toe 5th-side.

In an attempt to reveal the underlying structure of similarity judgements by using women's garment, we have applied the multi-dimensional scaling technique to the data. Through interpretation and comparison of derived spaces, it was found that there was a 5 noticeable effect between the similarity judgements. Effective dimensions affecting perception of women's garments are on intuitive perception of length of skirt and collar, form of women's garments, tone of color and opening, silhouette, and hue of color. Weights in each dimensions follow, commonly as a rule, in order of the spatial representation in perceived women's garments.
