Abstract
Abstract A temporary covering for feet in cold and wet weather conditions is formed by two identical boots each having a pair of foot shaped plastics members sealed together along substantially their entire periphery leaving only foot entry openings. Together the side members define a sole for the boot. Each boot has at least one tie loop with a tie ribbon passing therethrough. Each boot also has an insert member of generally foot shape received in the boot and which, when rotated to lie generally against the sole portion of the boot shapes the boot into wearable condition. Each boot has a plurality of antiskid strips adhered to the bottom outer surface of the sole portion.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
165 words
A temporary covering for unshod feet in cold and/or wet conditions comprising: a pair of boots each formed by a pair of mirror image members of substantially uniformly thick material sealed together along substantially their entire periphery leaving only a foot opening to each boot; each said member defining a sole portion having adhered on the outer side thereof a plurality of antislip members in a patterned array; each said member having at least one tie loop; a tie ribbon of sufficient length to secure said boot on a foot passing through each said loop; and an insert member formed from material having both insulating and cushioning properties and cut out to have the general outline of a foot, whereby said boot can be carried and stored in a compact condition with the insert rotated to lie substantially parallel to the planes of the members and opened into usable condition by rotating the insert to lie inside the sole portion thereby to shape the boot.
Claim 2
Dependent Claim
165 words
A temporary covering for unshod feet in cold and/or wet conditions comprising: a pair of boots each formed by a pair of mirror image members of substantially uniformly thick material sealed together along substantially their entire periphery leaving only a foot opening to each boot; each said member defining a sole portion having adhered on the outer side thereof a plurality of antislip members in a patterned array; each said member having at least one tie loop; a tie ribbon of sufficient length to secure said boot on a foot passing through each said loop; and an insert member formed from material having both insulating and cushioning properties and cut out to have the general outline of a foot, whereby said boot can be carried and stored in a compact condition with the insert rotated to lie substantially parallel to the planes of the members and opened into usable condition by rotating the insert to lie inside the sole portion thereby to shape the boot.
