Abstract: The boot includes a heel portion which together with a sole and vamp define a space for accommodation of a wearer's foot. A stiff inner upper is integrally connected to the vamp and heel portion and a stiff outer upper surrounds the inner upper. The outer upper is connected to the inner upper at the rear of the boot only and is free to move in the forward and rearward direction relative to the inner upper but is substantially immovable relative to the inner upper in the lateral direction.

Abstract: The fastener is formed within a protective helmet provided with a crown suspension and a head suspension. The crown suspension has a central portion adapted to contact the top of a wearer's head and has radially outwardly extending legs. The head suspension includes an outer strap which encircles the wearer's head at approximately the level with respect to the wearer's head of a normal hat band. A barb is joined to the end of each leg and tapers in thickness from its juncture with the leg to its end. A barb is also joined to a portion of the strap at its upper edge and likewise tapers in thickness from its juncture with the strap to its end. A number of flaps are connected to the inside wall of the helmet. Each flap has a slot through which the leg and strap extend, and above which the barbs connected to the straps are positioned. The barbs connected to the legs are accommodated in the space between the flaps and the inside wall of the helmet.
