| Abstract: |
A footwear article and the method of making the same which will allow water vapor due to perspiration to transpire through the article but will prevent liquid water from external sources from reaching the wearer's foot. One form of the footwear article of the invention comprises a sock which is of three-ply construction with the inside and outside plies being knit and the intermediate ply being made from an elastomeric polyurethane film. The three plies are uniquely bonded together using a pliant, waterproof adhesive.

I claim:
1. A method of making a waterproof footwear article constructed of an inner fabric sock, an outer fabric sock and an intermediate pliant, waterproof, breathable bladder having a continuous extremity receiving portion in the general shape of the wearer's foot and having a continuous inner and outer surface, said method comprising the steps of:
- (a) applying a thin layer of heat activated adhesive over the outer surface of the inner fabric sock to form a coated inner sock;
- (b) placing the bladder over the coated inner sock to form a subassembly;
- (c) applying a thin layer of adhesive over the inner surface of the outer fabric sock to form a coated outer sock;
- (d) placing said coated outer sock over said subassembly so that said layer of adhesive is proximate said bladder to form a precursor article; and
- (e) heating said precursor article to a temperature sufficient to activate said heat adhesive whereby said inner and outer socks will be adhesively bonded to the continuous inner and outer surfaces of the bladder.
