Adjustable Ankle Brace System (A.A.B.S) is a unique, neoprene-constructed ankle brace featuring a patented three-strap system that can be worn over virtually any athletic cleat. The durable bladder cloth stirrup fits between the front and back cleats on the sole of the shoe. The heavy-duty elastic pulley system creates firm but flexible support while the donut-type cushion protects the Achilles tendon. Its over-the-boot design improves comfort and will not affect the fit of your boot.
