ABSTRACT:
A shoe with a central closure attached to an instep cover, to which a wire-like tightening element is coupled and from which the tightening element runs back and forth between guide elements on side parts of the shoe upper and guide elements on the instep cover along the throat area of the shoe, where the guide elements on both sides of the shoe are connected, via a tensioning strip, with at least a pair of instep supporting straps which run over the side parts of the shoe upper from at least an edge area of the sole is improved by combining the instep supporting straps and the tensioning strips into a structural unit for each side of the shoe. Furthermore, the thickness of the instep supporting straps and the tensioning strips and/or the material properties of these parts is/are selected so that the tensioning strips have a greater stiffness than the supporting straps, and the tensioning strips, at least in the area of the guide elements is formed of a material that is abrasion-resistant, hard and has good sliding properties, i.e., a low coefficient of friction.
