Abstract
Abstract An improved golf shoe construction of the so-called "soft" variety. This golf shoe includes a sole comprised of an outsole layer and a midsole layer between which a plurality of spike retaining sockets are located. Attached to the midsole is a wedge shaped heel piece. According to one aspect of this invention, a cross shaped stabilizer shank is affixed between the midsole and heel piece. This shank design provides improved lateral arch aid support and enhances the torsional stiffness of the shoe. According to another aspect of this invention, the outsole and midsole are stitched and bonded together thus providing redundant attachment means thereby preventing delamination.
