Abstract

A boot having a flexible upper for snowboarding. The boot includes a flexible upper portion and a rigid reinforcing frame, wherein the rigid reinforcing frame includes a lower reinforcement portion surrounding the heel at least; a dorsal reinforcement portion surrounding the rear area of the lower part of the leg; both parts are connected via a narrow connecting portion that includes, on the lateral side, a stiffening arrangement that stiffens the connecting portion only during lateral tilting of the dorsal reinforcement portion on the lateral side of the boot. Because of the aforementioned construction, the boot retains its qualities of comfort and, at the same time, ensures the transmission of the essential forces by virtue of a frame that provides flexibility on the medial side of the boot and support on the lateral side of the boot.
