Abstract: A heater device particularly for ski boots, which comprises, located on the inner shoe of a ski boot, an electric resistance heater positioned at the user's foot sole and connected to a storage battery accommodated inside said inner shoe. The storage battery is connected to a recharge socket located at the top portion of said shoe and is connected to the resistance heater through a switch. Also provided is a voltage limiter adapted to prevent the storage battery from being discharged to below a preset voltage level.

Abstract: The device comprises a pressure band engageable with the front upper portion of an inner shoe attached with one end to a side area of the boot, whereas the other end thereof is connected to a tension band, effective to be operated by a skiing stick. On the tension band there acts a releasable lock serrated portion adapted to allow the free translatory movement of the tension band in one direction and to prevent the translation of the tension band in the opposite direction. Tension on the tension band causes compression of the inner shoe by the pressure band against the user's foot.

Abstract: A device for adjusting the inclination of a ski boot cuff comprises an abutment block effective to be engaged at different heights on the rear portion of the ski boot shell to contact the cuff such as to vary, in the rest condition, the inclination between the longitudinal centerline of the skier's leg wherewith the cuff is associated and the longitudinal centerline of the shell.
