Abstract
The invention relates to a sports shoe (1), in particular an alpine ski shoe (2), with an adjusting means (3) for varying the stiffness of the sole system (4) as and when necessary. This adjusting means (3) comprises at least one profiled tension element (19) which remains essentially dimensionally stable when forces act on it and which is connected at its oppositely lying end portions to a front sole platform (10) on the one hand and to a rear sole platform (11) of the sole system (4) on the other hand, its middle portion extending freely between the front and the rear sole platform (10, 11). The tension element (19) is mounted so as to be relatively displaceable in the longitudinal direction of the sole system (4) in order to apply adjustable positioning forces relative to at least one sole platform (10, 11), and an individually adjustable tensing force can be expended between the front and the rear sole platform (10, 11) via the tension element (19). This tensing force can be adjusted so that at least one load-induced tendency of a distance (25) between the front and rear sole platform (10, 11) to become bigger is counteracted or a tendential vertical lifting of the middle portion of the sole system (4) is induced.
