A shoe comprises a closure device, an upper made of flexible material which yields to the tensile stresses in the region of the closure and an instep shield which covers the instep. The instep shield can be attached on both sides to side side parts of the upper. To enable the instep shield and the side parts of the upper to be clamped together with a closure or clamping force as uniform as possible over the whole closure region, the end (5) of the instep shield (2) nearer the tip is movably connected on either side to closure flaps (3, 4) made from resilient material which are essentially parallel to, or make a small acute angle ( alpha ) with, the instep shield (2). Alternatively, each of these parts (2; 3; 4) consists of a separate component. The instep shield (2) has a central turnbuckle (12) with at least one tensioning element (11) which enables the closure flaps (3, 4) and the side parts (7) of the upper (8) to move relative to the instep shield (2). The tensioning element (11) connects the closure flaps (3, 4) to the instep shield (2) at least in the upper and lower parts (27, 28) of the instep shield (2) without crossing. |
