Abstract
Abstract This invention relates to ski-boots of the kind comprising a bottom part to carry the foot and an ankle cuff which is pivotable on said bottom part of the boot about a first pivot shaft extending transversely to the longitudinal direction of the boot, both said bottom part and said ankle cuff being made from a rigid material. According to the invention, the ankle cuff has plane side-walls arranged parallel to and at a distance from one another which rest against the insides of plane side-walls sections of the bottom part of the boot which are respectively associated with them; the first pivot shaft connecting the ankle cuff and the bottom part of the boot is arranged above the sole of the boot and to the rear of an axis aligned with the ankle joint of the intended wearer, (i.e. 5 to 10 cms above the boot sole), and at the front end, the ankle cuff has a transverse pin orientated parallel to the first pivot shaft whose ends are guided in a guide track of curved configuration in the bottom part of the boot.
