Abstract
A process for manufacturing a waterproof and vapor-permeable shoe is provided. In the process, an adhesive layer is provided on a knitted fabric to form a laminate, and a shoe upper unit is formed from the laminate, and has an adhesive component defining an inner space of the shoe upper unit. A shoe lining member, which is worn on a last, is placed into the shoe upper unit to permit a knitted component of the shoe upper unit to be bonded to the shoe lining member through the adhesive component under a heating treatment.
