ABSTRACT:
Footwear, such as a shoe (1) having a flat inner surface (5) and between said flat inner surface (5) and the instep a flat layer (6,12) of constant thickness for support of the foot, which flat layer (6,12) is of a highly springy elastic material with a high elastic recovery capacity, such as high density polyurethane foam. This flat layer requires the shoe to be made upon a last which allows sufficient space between instep and flat layer and accordingly is larger than is usual for a given size.
