3. Setup and Application
Follow these steps to properly apply your Aircast AirSport Ankle Support Brace:
- Prepare Your Foot: Ensure your foot is clean and dry. It is recommended to wear a sock for comfort and hygiene.
- Step-In Application: Open all straps on the brace. Slide your foot into the brace, ensuring your heel is seated firmly in the heel cup and the brace's side supports align with your ankle bones. The brace is designed for a step-in application.
- Secure the Forefoot Wrap: Wrap the forefoot strap around the front of your foot and secure it. This helps position the brace correctly.
- Adjust Heel: The brace features an automatic heel adjustment. Ensure the heel is comfortably snug.
- Fasten Shin Wraps: Secure the integral shin wraps around your lower leg.
- Apply ATF Cross-Strap: Take the Anterior Talofibular (ATF) cross-strap and wrap it across the front of your ankle, securing it to the opposite side. This strap provides additional stabilization. Adjust for firm, comfortable support without restricting circulation.
- Final Adjustments: Walk a few steps to ensure the brace feels comfortable and supportive. Readjust straps as necessary. The brace should feel snug but not painful or restrictive.
