Per the ASO Co website: “The ASO Ankle Brace will help offer additional support and protection to an injured or sore ankle and foot. Featuring a ballistic nylon boot, the ASO brace is incredibly strong and durable for long-lasting use. The bilateral design means that the ASO ankle stabilizer can fit either the right or left foot, while the low profile makes it great to use with any type of shoe. For the best protection and ankle support, the ASO brace features stabilizing straps and elastic cuff closure. Keep your ankle supported with the ASO Ankle Brace.”
