Sixty feet of 30 normal subjects were investigated to determine the ef
fect of changing the heel height on forefoot loading. Subjects walked
across footplates barefoot and with rigid polyurethane heels attached
to the foot with a tubular bandage. The total load on the forefoot rem
ained unchanged at all of the heel heights, but the distribution of th
e load changed as the heel was raised. The area of forefoot contact wi
th the footplates decreased and there was a deviation of load toward t
he medial side of the forefoot with a resultant increase in pressure.
These effects could contribute to overload of the distal forefoot and
especially of the first ray.
