Abstract
Abstract An inner sole for footwear comprising a shaped element having a contour which reproduces the profile of the foot and which includes a heel portion, an arch portion and a toe portion. The shaped element has a lateral wall encompassing the contour at the lateral edges thereof, extending from the heel portion to the toe portion to confine and hold the foot of the wearer laterally. The heel portion is provided with a depression into which the heel of the foot of the wearer is received and held. The lateral wall extends substantially vertically from the depression at the rear thereof. The depression extends upwardly and forwardly to merge smoothly with the arch portion. The toe portion includes a transversely arranged raised portion having corrugations to receive the toes of the foot of the wearer.
