ASO Ankle Brace – Lace-Up Ankle Stabilising Orthosis
The ASO (Ankle Stabilising Orthosis) is the most widely prescribed lace-up ankle brace in sport and clinical settings worldwide. Its combination of a lace-up front panel with bilateral figure-of-eight stabilising straps delivers firm medial and lateral support while still allowing functional movement for walking, training and competition.
Whether you're returning to sport after a lateral ankle sprain, managing chronic ankle instability, or need dependable support for a physically demanding job, the ASO provides structured, repeatable bracing that fits inside most shoes without adding bulk.
Key Features
- Bilateral stabilising straps — figure-of-eight configuration mirrors the support of a professional ankle tape job
- Lace-up front panel — adjustable compression for a secure, custom fit every time
- Low-profile design — fits inside athletic shoes, work boots and most everyday footwear
- Ballistic nylon construction — durable enough for daily use through a full sports season
- Boot-style design — quick to apply and remove compared to traditional ankle taping
- Functional range of motion — restricts harmful inversion/eversion while allowing dorsiflexion and plantarflexion for normal gait
ASO Ankle Brace vs Ankle Taping
Professional ankle taping provides excellent initial support but loses up to 50% of its effectiveness within 20 minutes of exercise as the tape loosens. The ASO can be re-tightened at any time and provides consistent support throughout an entire game, shift or training session — at a fraction of the ongoing cost of athletic tape.
Sizing
Measure around the ankle at the narrowest point above the ankle bones. Select your size based on the circumference. The ASO is available in sizes XS through XL and is sold as a single brace (fits left or right ankle).

Frequently Asked Questions
Can I wear the ASO ankle brace for sport?
Yes — the ASO is specifically designed for use during sport. It's widely used in basketball, netball, soccer, AFL and volleyball. The low-profile design fits inside most athletic shoes and the stabilising straps provide support without significantly restricting normal running and jumping movement.
Is the ASO good for chronic ankle instability?
Yes — the ASO is one of the most commonly recommended braces for people with recurring ankle sprains or chronic ankle instability. The figure-of-eight strap configuration provides consistent medial-lateral support that can help reduce the risk of re-injury.
Can I wear it on either ankle?
Yes — the ASO is designed as a universal brace that fits both left and right ankles.
How long does an ASO ankle brace last?
With regular use and care, an ASO typically lasts an entire sports season (3–6 months of heavy use). Many users get longer life with less frequent wear. It's machine washable on a gentle cycle.
Is the ASO better than a neoprene ankle sleeve?
They serve different purposes. A neoprene sleeve provides compression and warmth but minimal structural support. The ASO provides firm mechanical stabilisation with its lace-up and strap system — it's the better choice when you need to prevent ankle rolling or are returning from a sprain.
