Abstract
A padding is disclosed for an orthopedic support device including a resiliently deformable foamed plastic layer and a fabric layer laminated to at least one surface of the foam layer to provide an inner surface of the padding for placement against a body member. A plurality of dimples are provided in the inner surface to form air spaces adjacent the body member. Openings are provided in the dimples which extend through the thickness of the foam layer and the fabric to provide airflow between the air spaces and the outside air. In a preferred embodiment, the foam layer comprises a non-clickable ester foam, and the dimples are dimensioned and arranged so that at least a portion of the dimples merge with adjacent dimples to facilitate air movement between the air spaces of the merged dimples.
