Abstract
Abstract According to the invention a boot is provided which includes a shell base having an inner sole mounted therein. Additionally, the boot includes a foot retention system positioned within the shell base; the foot retention system including at least one support element positioned between the shell base and the area in which a foot is to be inserted. The support element is adapted to at least partially cover the foot. An adjustable tightening apparatus serves to tighten the support element around the foot. The tightening apparatus includes pressurization means for pressing the support element against the foot and adjustment means for adjusting the pressurization means. The boot apparatus is such that the pressurization means exerts pressure directly on a front portion of the foot, and extends generally from the inner sole of the boot to the upper portion of the foot.
