Figure 3.

Map of peak plantar pressures during barefoot walking over a pressure platform system. The solid straight line is the longitudinal axis of the foot through the second metatarsal and digits. The curved line is the center-of-pressure (COP) line. The COP line is lateral to the longitudinal bisection of the foot in the hindfoot and the midfoot and crosses the midline in the late stance phase (toe lifting off) of walking. L=length, M01=medial half of foot, M02=lateral half of foot, W=width.
