Short Description
The Med Spec ASO Ankle Stabilizing Orthosis is the leading professional brace for subtalar and talocrural joint stabilization. Its patented Figure-8 straps contour above the malleolii to replicate athletic taping and prevent inversion/eversion sprains. Durable, low-profile ballistic nylon design fits easily in any shoe. Bilateral: Fits Left or Right.
The Med Spec ASO Ankle Stabilizer is the industry-standard lace-up ankle orthosis, trusted by collegiate and professional athletes, athletic trainers, and orthopedic surgeons worldwide. Designed to provide superior medial and lateral support, the ASO effectively mimics professional athletic taping to stabilize the subtalar and talocrural joints.
Technical Features Of the Med Spec ASO
-
Ballistic Nylon Construction: The main boot is made from ultra-durable, high-strength ballistic nylon to resist stretching during heavy activity.
-
Patented Figure-8 Strapping: Non-stretch nylon straps form a complete figure-eight, providing the same lock-down support as athletic tape without the need for re-taping during a game.
-
Anatomical Malleolii Contouring: Angled stabilizing straps sit comfortably above the ankle bones (malleolii) for enhanced comfort and reduced pressure points.
-
CoolFlex™ Achilles Pad: Specialized padding along the Achilles tendon and tongue provides superior comfort and prevents lace-bite.
-
Low-Profile Bilateral Design: Fits easily in most footwear, including cleats and court shoes. Fits both the Left and Right foot.
-
Recommended HCPCS Code: L1902
- Available sizes: XXS (Pediatric), XS, Small, Medium, Large, XL, XXL, XXXL

Available Versions: Standard vs. With Stays
We offer the original ASO Ankle Stabilizer (standard lace-up) and the ASO with Plastic Stays for maximum, acute protection.
Note: The version with plastic stays includes two removable semi-rigid inserts (one medial, one lateral). These stays provide superior proprioceptive protection and are often recommended during the acute phase of an ankle sprain. They can be removed as the user transitions into rehabilitation or returns to sport.
