A footwear construction that includes an improved footwear upper liner is provided. The liquid impermeable footwear upper liner is constructed of air permeable, waterproof and moisture vapor transmissive materials as well as air impermeable, waterproof and moisture vapor impermeable materials. A process for constructing a footwear component utilizing the improved footwear upper liner is also provided. The process comprises providing a sole; providing an upper that together with the sole define a volume for receiving and protecting a wearer's foot against external elements and securing the improved liquid impermeable footwear upper liner within the footwear so that the footwear upper liner is located underneath the upper. In an alternative embodiment, the improved footwear upper liner is attached to a sole to form a bootie for use in footwear construction.

Waterproof footwear construction

A garment (20) for inhibiting relatively moving air from contacting a portion of a person wearing the garment. The garment (20) comprises a first panel (22) for inhibiting relative air movement contact against a portion of the body of the person. The first panel (22) includes a first fabric layer (62), a second fabric layer (64) and a first membrane (66) located between the first and second the first fabric layers. The first membrane (66) is water-resistant. The first panel (22) has an air permeability of not more than 3 CFM/ft.sup.2 and a moisture vapor transmission rate of at least 800 gm/m.sup.2 .multidot.day. The garment (20) also comprises a second panel (24) connectable with the first panel (22). The second panel (24) includes a third fabric layer (62a), a fourth fabric layer (64a) and a second membrane (66a) located between the third and fourth fabric layers. The second membrane (66a) is water-resistant. The second panel (24) has an air permeability of at least 6 CFM/f.sup.2 and a moisture vapor transmission rate of at least 1000 gm/m.sup.2 .multidot.day.
