- 1. A shoe, which comprises a shoe upper having marginal portions for attachment to an outsole, and a moulded outsole directly secured to said marginal portions which incorporates stiffening means (8;22,23) comprising one or more preformed components (10, 11;22,23) embedded in an outsole body moulded thereabout, the stiffening means having a first portion (10;22) operative to stiffen a waist or shank of the outsole and a second portion (11;23) operative both to stiffen a fore-part of the outsole, though to a lesser extent than the first portion stiffens the waist or shank, and to provide resilience to cause or assist in the return of the fore-part of the outsole to or towards an unflexed state after being subjected, in use, to transverse flexure as the result of flexure of the user's foot at the ball of the foot, characterized in that said moulded outsole body has an upper surface and a bottom surface and is formed with an opening therein between laterally spaced side portions of the waist or shank, and said stiffening means includes a portion projecting downward through said opening and exposed at the bottom surface of said outsole body and an upper surface portion flush with and at least partially exposed at the upper surface of the outsole body and forming a weight-bearing surface.
- 2. An outsole according to claim 1 in which the forward end of the first portion (10) is integral with or united to the rearward end of the second portion (11).
- 3. An outsole according to claim 1 in which the first portion (10) is of progressively reduced cross-section towards its forward end so that its stiffness is progressively reduced.
- 4. An outsole according to claim 1 in which the second portion (11;23) comprises two or more elements (15) which are laterally spaced apart and extend generally lengthwise of the fore-part of the outsole.
