Abstract
Abstract This invention relates to boots for divers, used in association with a wet suit, dry suit, other diving gears or for other aquatic activities. Each boot comprises a sock, made of elastomeric material, preferably covered by nylon fabric on one or two sides, and an outsole, together with a back stay, a toe-cap and a foxing, made of non-cellular rubber and directly vulcanized as a unit on the sock. The resulting boot is long-lasting because the outsole does not become detached from the sock. Vulcanization is carried out in such a way that it does not affect the cellular elastomeric material.

Claim 8
Dependent Claim
135 words
A boot for divers comprising a sock and an outsole assembly, said sock made of a central layer of cellular neoprene having an inner and an outer surface, an inside and an outside fabric adhering to said central layer over the entire inner and outer surfaces of said central layer, said sock forming an inner sole and an upper, being completely closed, except for a top opening for the passage of the user's foot, and made of two half-parts stitched together by a line of stitching extending in the central, vertical plane of the sock, said outsole assembly consisting of a major part of a natural, non-cellular rubber composition and covering the insole and the adjacent part of the upper all around the insole, said outsole assembly vulcanized in situ and adhering to the sock.
Claim 9
Dependent Claim
135 words
A boot for divers comprising a sock and an outsole assembly, said sock made of a central layer of cellular neoprene having an inner and an outer surface, an inside and an outside fabric adhering to said central layer over the entire inner and outer surfaces of said central layer, said sock forming an inner sole and an upper, being completely closed, except for a top opening for the passage of the user's foot, and made of two half-parts stitched together by a line of stitching extending in the central, vertical plane of the sock, said outsole assembly consisting of a major part of a natural, non-cellular rubber composition and covering the insole and the adjacent part of the upper all around the insole, said outsole assembly vulcanized in situ and adhering to the sock.
Claim 10
Dependent Claim
68 words
A boot for divers as defined in claim 7, further including a first coat of neoprene base cement coating said outside fabric and said central layer through the interstices of said outside fabric, said first coat coating said insole and said adjacent part of the upper, and a second coat of natural rubber base cement applied to said first coat and in direct contact with said outsole assembly.
Claim 11
Dependent Claim
63 words
A boot as defined in claim 7, wherein said outsole assembly includes an outsole extended by a back stay at the heel of the boot, by a toe-cap at the toe portion of the boot and by a foxing along the lower edge of the boot all around the same, said back stay, toe-cap and foxing forming an integral assembly with said outsole.
