Abstract
Abstract An athletic shoe suitable for use on artificial turf is described including an improved upper of a porous multiple layer construction and an improved sole having integral polygon shaped studs. The upper is preferably made of nylon tricot fabric outer layer, a polyurethane foam middle layer, and a porous synthetic fabric inner layer. This greatly reduces the weight of a football shoe made in accordance with the invention so that it is approximately one-half the weight of a conventional leather football shoe as well as providing great comfort and enabling use in wet weather without damage. The sole has short multi-sided polygon shaped studs of square, rectangular or triangle cross section, having a plurality of flat sides which provide gripping edges that give greatly improved traction.
