A wedge heel is attached to the insole at the heel seat thereof, and a wedge tunnel cover is attached to the front face of the heel and the bottom of the insole forward of the heel. The rear edge of an outsole covers the front edge of the wedge tunnel cover and stitching may be used to lock the insole, the outsole, the wedge heel and the wedge tunnel cover together so that they adequately support the weight of the wearer.
