ASO Flex-Hinge Ankle Brace

The ASO Flex-Hinge Ankle Brace combines the proven technology of the ASO's patented strapping system with an articulated plastic shell for superior ankle stabilization. The internal plastic shell with hinge is built into a ballistic nylon boot and flexes to conform to the anatomy of the ankle.

  • Internal plastic shell: The upper portion of the internal plastic shell is incorporated into the eyelet lace closure to create an inner cuff around the tibia and fibula which resists separation of the tibia and fibula to help treat syndesmosis ankle sprains (high ankle sprains)
  • Internal plastic shell with hinge is built into ballistic nylon boot and flexes to conform to the anatomy of the ankle, which greatly enhances patient comfort and compliance
  • Stabilizing straps: Figure eight nylon stabilizing straps and elastic cuff work in conjunction with the internal plastic shell to capture the calcaneus and resist inversion or eversion motion
  • Bilateral design: Fits left or right foot
  • US manufacturing: higher quality control standards


  • ASO Flex-Hinge Ankle Brace is indicated for moderate/severe sprains
  • ASO Flex-Hinge Ankle Brace is used for immobilization following other ankle/foot injuries


  • Maximum stability
  • Prevent sprains/strains
  • Decrease anti-inflammatory medications
  • Decrease pain symptoms
  • Improve joint function
  • Maintain flexibility
