Boot for a binding

Abstract

The invention relates to a boot for a binding, which is suited for alpine skiing, ski touring, cross-country skiing, telemark skiing and also for other snow sliding sports, the boot having greater comfort in wearing and moving. Moreover multifunctional components make it possible for the overall equipment with which the snow sportsman is burdened to have low weight. The boot comprises an outer shell for holding the foot and a coupling part for fastening the boot in the binding, the boot being held in the boot tip region and in the heel region of the binding on the coupling part. The outer shell is movably connected to the coupling part, the connection of the outer shell to the coupling part being made such that in the state of the boot fastened in the binding the foot held in the outer shell together with the outer shell can be lifted in the heel region and lowered again in a walking motion. Furthermore the outer shell can be locked relative to the coupling part and there can be a climbing aid and a damping device for damping of the walking motion on the boot.
