Abstract
Abstract A ski boot has a base element forming sole, toe and instep portions and which mounts a shin cuff element, a calf cuff element, and a heel seat element with three triangularly located hinging connections. The heel seat element engages a wearer's heel to aid in closure of the cuff elements and to facilitate removal of the boot. A cuff closure automatically engages when the cuff elements are moved to closed positions, and is readily releasable for ease in boot removal. An adjustable instep closure automatically tightens, by way of strap elements coupled with the rear cuff element, upon closure of the boot. The closure mechanism relaxes the instep closure tension when the skier leans forward. The shin cuff element and the toe portion of the base element movably and replaceably seat a forward lean control element so that it may readily be removed and replaced, and the mounting can be adjustable for selecting the forward lean resistance.
