Abstract
An insole for use in a slipper is provided. The insole includes a first cushion layer and a second cushion layer. The first cushion layer includes a first foam layer and an air permeable membrane covering the first foam layer. The second cushion layer includes a second foam layer and an air permeable membrane covering the second foam layer. The first cushion layers are arranged so that the air permeable membrane of each layer faces outward, and the first cushion layer and the second cushion layer are attached together along their perimeter to provide a cavity between the first cushion layer and the second cushion layer. The insole can be referred to as pillow cushion because of the formation of a cavity between the first cushion layer and the second cushion layer. A slipper and a method for manufacturing a slipper are provided.
