📏Sizing Guide

Measure around your ankle at the narrowest point above the ankle bones. ASO braces fit inside most athletic shoes.

💡Tips & Tricks

Lace the brace like a shoe, then apply the figure-8 straps for extra support. The ASO is designed to fit inside your shoe.

⚠️Common Mistakes

Choosing a size too large reduces support. Make sure the figure-8 straps are used, as they provide most of the stability.

📏Sizing Guide

Aircast braces come in standard sizes based on ankle and shoe size. Some models are one-size with adjustable air cells.

💡Tips & Tricks

Inflate the air cells after putting on the brace for a custom fit. The air cells provide graduated compression to reduce swelling. Wear over a thin sock.

⚠️Common Mistakes

Not inflating the air cells means you are not getting the compression benefit. An Aircast is bulkier than a lace-up brace, so you may need a wider shoe.

📏Sizing Guide

Sized by shoe size and foot side (left or right). Check the manufacturer's chart and pick the side that matches your injured ankle. The brace is designed to fit inside a typical athletic shoe without needing extra width.

💡Tips & Tricks

Slip the A60 on like a sock, position the stabilizers along the sides of your ankle bone, then tighten the single strap across the top. The 60-degree stabilizers should sit right against the lateral and medial sides — not too far forward or back. Wear over a thin athletic sock for comfort.

⚠️Common Mistakes

Choosing the wrong side (left vs. right) reduces support. The A60 is anatomically shaped, so the wrong foot will leave the stabilizers in the wrong position. Skipping the strap tightening means the stabilizers won't stay in place during activity. For severe acute sprains with significant swelling, the classic Air Stirrup with adjustable air cells is usually a better choice.

📏Sizing Guide

Sized by shoe size and side. The Aircast AirLift PTTD brace sizes are: Small fits women's up to 8.5 / men's up to 7; Medium fits women's 9 to 12.5 / men's 7.5 to 11; Large fits women's 13 / men's 11.5 to 12.5. Pick left or right.

💡Tips & Tricks

The brace has a semi-rigid shell that wraps the ankle and an inflatable air cell under the arch. After putting the brace on, use the included hand bulb to inflate the air cell until you feel firm support lifting your arch — this takes pressure off the posterior tibial tendon. The rear-entry, two-strap design makes the brace easy to apply. Wear inside a roomy athletic shoe.

⚠️Common Mistakes

Skipping the air cell inflation eliminates the arch support that makes this brace different from a generic ankle brace. Wearing a regular lace-up or stirrup ankle brace instead of a PTTD-specific brace will not address the arch collapse. A shoe that is too tight will not have room for the brace.

📏Sizing Guide

Measure ankle circumference at the narrowest point above the ankle bones, and at the widest point of the foot at the arch. Match to the manufacturer's chart. The sleeve should fit snugly like compression wear without cutting in or bunching.

💡Tips & Tricks

Roll the sleeve on rather than pulling to avoid overstretching. The sleeve provides graduated compression and warmth, which helps reduce mild swelling and supports the joint during activity. Most patients wear them during exercise or long days on their feet, and remove them at night.

⚠️Common Mistakes

A sleeve that is too tight cuts off circulation and can cause toes to swell or turn cold. If you see skin bulging above the sleeve, size up. Compression sleeves are not a substitute for an ankle brace if you have a true injury or instability — they provide light support only.
