Abstract: A sock lining layer corresponding to the shape of a shoe is secured to one side of a foam layer of substantially the same size and shape. A backer layer is secured to the other side of the foam layer. The periphery of said layers are secured together. Slippage control between the sock lining and the foam layer is attained by stitching in the form of a closed loop wholly disposed at the location adapted to support a ball of a foot. The loop stitching has two extensions each extending from one end of the loop to the periphery of said layers at a location between the heel end of the layers and said one end of said loop.

Abstract: A mud guard is stitched to an upper at or spaced from the lower edge of the upper. A portion of the periphery of a sock lining is stitched to the lower edge of the upper but is free from attachment with respect to the heel portion of the upper. An inner sole or platform containing a metal shank is bonded to the sock lining. Then a free edge portion of the mud guard as well as a heel flange are lasted in overlying relation to the inner sole. Thereafter, an outsole is attached to the inner sole in overlying relation to the heel flange and mud guard.
