For use in a shoe which includes an outer sole having an approximately V- shaped ridge defining the salient rear end of the tread portion and the forward end of the shank portion of the sole, a wedge piece bearing on the innersurface of the outer sole, and having a salient thickened edge conforming to a portion of said ridge, and an inner *sole conforming to the inner side of said wedge piece; smolded' sheet metal shank stifiener, shaped at its forward end portion to bear on the inner side of the thickened rear portion of the wedge piece, and having a recess in its forward edge conforming a proximately to the salient edge of the we ge piece, the stiffener having a longitudinal rldge between its front and rear end portions, adapted to support a. lonitudinal ridge on the under surface of the s ank portion of the outer sole, said recess imparting transverse flexibility to-the forward end portion of the stiffener.

2. A shank stiffener substantially as specified by claim 1, provided, in a portion of said longitudinal ridge, with a longitudinal slot whereby longitudinal and transverse flexibility is imparted to the stifiener between its end portions, said slot being adapted to receive rivets connecting the shank portions of the outer and inner soles.

In testimony whereof -I have aifixed my signature.
