Abstract: A flex control device, for the quarter of a motocross boot, which comprises a soft upper provided at the rear with a semirigid cuff and a semirigid counter, which are connected respectively to the upper and to the upper and/or sole. The device is constituted by a first rod shaped element and a second rod shaped element, the first rod shaped element being rigidly coupled to the counter, the second one being selectively associable with the quarter, the first and second rod shaped elements being slidingly associated in contrast with at least one elastically deformable element.

Abstract: A sports shoe, comprising a soft upper provided with a cuff and with a rear counter which are semirigid and are separately connected to the upper, an additional semirigid element that is associated with the upper or monolithically coupled thereto, in an intermediate region, between the cuff and the counter, the additional semirigid element having, at the rear and/or laterally, at least one first tab and at least one second tab for sliding engagement in first guides formed in the cuff and in the counter.

Abstract: A sporting shoe equipped with a device to control the flexion of the toe includes a localized low friction protection body, particularly for a technical boot designed for practicing the sport of motorcycling, removable, attached along one side of the shoe with the use of reciprocal holder and engaging at least part of the point and of the side. The protection body is hinged to a second element, placed at the back, fixed along the external side of the shoe or a part of it, with the cooperation of a third element ovelapping the first two, which, engaging the second, provides two opposite stops that limit the run of the protection body and of the toe part of the relative shoe, or of a part thereof with respect to the back part.
