Abstract
Abstract A system for supplying air to the interior of a shoe, particularly of a skiing boot for Alpine skiing is disclosed. The shoe or skiing boot comprises a shell and a gaiter, which is pivoted to the shell and pivotally movable in the longitudinal direction of the shoe. An air-handling device is mounted on the shell of the shoe and is connected to actuating means. The latter is also connected to the gaiter and during a forward and rearward pivotal movement of the gaiter move up and down to impart a pumping motion to the air-handling device so that air is pumped into the interior of the shoe. The air inlet is preferably disposed near the sole of the shoe.

Claim 1
Independent Claim
183 words
In a ski boot of the type having a shell, a gaiter which is pivotally mounted on the shell and movable in the longitudinal direction of the boot, an inner shoe and a wedge-shaped hollow section below the outer portion of the sole of the inner shoe, a system for supplying air to the interior of the boot comprising: an air handling device mounted on the shell of the boot; an actuating means operatively connected at one end to the air handling device and connected at the other end to the rear side of the gaiter directly above the heel; one or more nozzles which are embedded in the walls of the inner shoe; one or more conduits for air passage which are connected at one end to the air handling device and at the other end to the nozzle; air passage openings in the top of the inner shoe on the side remote from the actuating means; and openings in the shell of the boot on the side remote from the actuating means for air exhaust to the outside of the boot.
