The subjects did not show any visible foot's abnormalities during a podiatric examination. The data were taken while the subjects walked normally wearing four different types of shoes and once with only a sock. Each time data were measured and recorded using the pedobarographics inshoe-insole data acquisition system that had 00 sensors spaced across each planar foot. The data were further reduced to display the gait line velocity for the various subjects as a function of shoe types. The gait line is the average instantaneous force over the planar foot as a function of time.
Results form the study indicate that there are definite dynamic patterns in the gait-line velocity.
A negative velocity is notable at heel strike and is more pronounced without shoe support. Without shoe support the peak velocity is higher and occurs earlier than with shoe support. The peak velocity occurs near the middle of the stance phase.
