Memory foam is inserted into the upper by hand, for a pillowed comfort that allows the shoe to mold to your foot for a perfectly cushioned fit. Roams custom contoured footbed provides supportive cushion and is lined in moisture wicking, breathable neoprene fabric to keep feet comfortably and dry. The durable, high-flex, tread outsole provides stability and is made of sustainable BIO EVA derived from sugarcane, something we can all feel good about as we ROAM.
