Claims16
A boot comprising an inner member and an outer member configured for releasable securement about said inner member, said outer member including a sole, a flexible upper, and a protective cage incorporating a substantially rigid toe portion, an arch portion and a heel portion, said arch portion and said heel portion of said cage being adapted to be interposed between said inner member and said outer member, the inner member having an upper and a sole, a heel and a toe portion, said sole, heal and toe portions of said inner member being formed from resiliently deformable material which is affixed to said inner member upper, said inner member upper having a longitudinal axis and being formed of material capable of stretching in a lateral plane to an extent necessary to permit passing of a foot therethrough while being relatively inextensible along its longitudinal axis in order to allow said inner member upper to be pulled vertically without significant stretching during introduction of the foot through said inner member;
- releasable locking means for locking said inner member to the protective cage;
- and locking means for locking said protective cage to said outer member.
