Abstract
Abstract A ski boot provided with an external reinforcing structure which permits forward bending of the leg relative to the foot of the wearer, i.e., the normal movement carried out during skiing, said reinforcing structure being removable to permit the boot to be made of softer material than that normally used for ski boots so that the ski boot when used for walking without the reinforcing structure affords the same convenience to the wearer as a normal shoe for walking.
