Apply an ace bandage or a sock to the affected foot and ankle. A white athletic or tube sock is preferred as the dye in dark socks can stain the skin from perspiration. If you are using an ace bandage, be sure to wrap it comfortably to avoid unnecessary swelling.

Open the Aircast ankle brace and determine the inner and outer sides. The heel strap has a rounded edge to it that denotes the "rear" of the brace. It should be positioned to correspond to the rounded portion of your heel.

The brace comes with its side pads pre-inflated with air. It also comes with a small tube to allow for adding or removing air from the padded sides. For the most part, however, you shouldn't need to adjust the amount of inflation.

Place your foot into the brace and rest it on the floor. The ankle and foot should be at a 90-degree angle to each other, if possible This sets the foot in a position to allow for wrapping of the straps around the ankle. Start with the bottom strap and work upward. This makes for a more secure fit 1. Wrap straps just tightly enough to prevent slippage.

Don't over-inflate padded side panels. This increases the distance between the body and the brace and compromises the level of support.
It's generally recommended that you not apply the brace directly to the skin as it can cause blistering.
