FREEDOM Full-Contact Insoles feature a deeply cupped, stabilizing heel and moderate longitudinal arch that combine to provide outstanding fit and relief. Resilient and conforming materials protect and accommodate insensitive feet. The top or footbed layer is a full 1/4″ of LD45 Pink Plastazote, which has long been the material of choice for moldable contact with the foot. Hypoallergenic and highly heat moldable, this material does not support fungus or bacterial growth. The second full-length mid-layer is 1/16″ of PORON Cushioning , that resists bottoming out of the upper Plastazote layer. The base material is a firm, supportive 1/4″ ProCell EVA extending from heel cup to just behind the metatarsal heads. Sizing: Based on shoe size: X-Large Men’s 12 – 13
