The present invention is footwear having a convex shaped outsole with opposing wedge shaped configurations in the bottom of the front sole section and the back sole section which provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The present invention is also footwear convex shaped in the longitudinal direction with a split sole having opposing wedge shaped configurations in the bottom of the front sole section and the back sole section that provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The invention further includes footwear having at least one pair of wedges on the outsole which provide footwear having improved arch support. The invention is also footwear with a flexible, elastic, member between the front sole section and the back sole section of the sole.

A traction stud comprises: a carrier comprising a post, a hollow defined by the post that opens at a distal end of the post, and a multi-pronged flange at a proximal end of the post; and a tip bonded in the hollow and extending past the distal end of the post. The carrier may be metal and/or the tip is ceramic. The multi-pronged flange may comprise two or more prongs, each prong having a first face, a second face, a thickness, and one or more holes extending from the first face to the second face, wherein the first and second faces are substantially perpendicular to the post. Outsoles comprise the traction studs and boots and/or overshoes comprise the outsoles. The traction studs are securely retained by polymeric material of the outsoles. The studs penetrate and/or grip slippery surfaces such as ice and packed snow.

Provided is a shoe with a replaceable screw-on heel.

Provided is a shoe with a replaceable screw-on heel.

An article of footwear is disclosed having at least one elongated heel support member. The elongated heel support member may be angled and extend from a heel region to a midfoot region, in order to disperse forces applied by a wearer's heel during movement. The heel system may include two heel support members, each associated with a side of the article of footwear. The article of footwear may also include a series of ribs in the midfoot region, which may abut a front edge of the heel support members. Finally, the article of footwear may include asymmetric side flaps extending downward from an upper plate so as to overlap a midsole.
