The RocketSoc is an ankle support designed for use in the treatment or prevention of ankle sprains. It is held in place with adjustable Velcro straps, and can be worn inside an athletic shoe. Peroneal forefoot and calcaneal heel lock straps provide support to control abnormal plantar flexion and inversion without restricting range of motion. The toes are left free. Available for the left or right foot, this ankle support is available in nylon lace-up, neoprene, or Drytex. The neoprene model, made of four-way stretch material, provides even compression for acute ankle injuries, with an optional inferior buttress to help control swelling. The Drytex model is constructed with a nylon core and polyester Lycra fabric that allows for airflow to keep ankles cool and dry. DIMENSIONS: Neoprene is 1/8 inch thick. SIZES: Extra small (shoe size 4 to 5 1/2), small (shoe size 6 to 7 1/2), medium (shoe size 8 to 9 1/2), large (shoe size 10 to 11 1/2), extra large (shoe size 12 to 13 1/2), or extra extra large (shoe size 14 to 16). COLORS: The neoprene support available in black, blue or white; the nylon lace-up is available in black or white; and Drytex is available in black only.
