The original "Swede-O" ankle brace is the #1 choice for ankle protection! The dual eyelets create a "pulley" effect to give you greater leverage so you can lace the brace tighter for a more effective "Ankle Lok". Stainless steel spiral stays are sewn into the medial and lateral sides of the brace for support. The Ankle Lok's removable side stabilizers offer additional support for weak or injured ankles. The full elastic back is comfortable against the Achilles tendon and helps reduce irritation and potential for blistering. The durable vinyl construction and industry-leading 1-year warranty provide peace of mind that you're giving your ankle the best protection. This brace fits comfortably in most athletic shoes.
