DESCRIPTION:

BRIEF SUMMARY
The present invention relates to boots of the type having a separate and distinguishable inner and outer boot with a protective cage there between. For a number of years it has been common to provide footwear with an inner and an outer boot in order that precise fitting may be achieved by varying the size of the inner boot whilst maintaining a limited range of outer boot sizes in stock. The outer boot may additionally be tailored to specific uses without varying the design of the inner boot. This method of construction of boots has for some years been quite popular in relation to ski boots and in-line skates. Protective footwear has also utilised such a system with a protective cage designed to protect one or more of the wearer's arch, toes or heel interposed between the inner and outer boot. The lastmentioned type of boot can use a very flexible outer boot upper in order to render it waterproof without adding significantly to the weight of the boot although such boots often have cumbersome arrangements for tightening the upper boot around the wearer's shin.
It is accordingly an object of the present invention to disclose improved systems for manufacturing footwear of the type described or at least to provide the market with an alternative.
According to one aspect of the present invention there is disclosed an inner boot having a sole, heel and toe portion formed of resiliently deformable material bonded or otherwise affixed to a sock-like upper; the upper being formed of material capable of stretching in a lateral plane to an extent necessary to permit passing of a foot therethrough whilst being capable of contracting back to a snug position about the wearer's lower calf and shin; the upper being relatively inextensible in a vertical direction to allow it to be pulled vertically without significant stretching during the introduction of the wearer's foot through the upper opening; there being an external lateral protrusion from the resiliently deformable heel portion of the inner boot adapted to co-operate with an indent in the outer boot in order to prevent relative movement between the inner and outer boot.
According to another aspect of the present invention there is disclosed a sizing and comfort spacer adapted for affixation about the inside of the arch protecting portion of a protective cage.
According to a further aspect of the present invention there is disclosed an outer boot having an upper portion adapted to fit about the lower shin and calf of a wearer constructed from thin fabric having little form memory; the rear portion of the upper of such outer boot being reinforced by resiliently deformable material in the area of the Achilles tendon and extending to a position adjacent the upper extremity of the boot upper; the upper area of such resiliently deformable reinforcement carrying fastening means adapted to releasably engage complementary fastening means adjacent the top of each side of the material comprising the upper extremity of the boot; the mating of the fastening means being adapted to secure the material comprising the upper extremity of the boot snugly about the wearer's calf and shin whilst the undoing of such fastenings permits opening of the upper extremity of the outer boot so as to facilitate removal or introduction of the wearer's foot.
A number of aspects of the present invention will be described with reference to the accompanying drawings in which:
FIG. I is a perspective view of an inner boot constructed in accordance with the present invention;
FIG. II is a perspective view of a protective cage in accordance with the present invention;
FIG. III is a section through the arch protector of the protective cage of FIG. II;

FIG. V is a section through an assembled inner and outer boot combination in accordance with the present invention; and
FIG. VI is a schematic view of the upper portion of an inner and outer boot in accordance with the present invention.
According to the embodiment of FIG
