Do Ankle Braces Actually Prevent Sprains? Here's What the Research Says

Ankle sprains are one of the most common injuries in Australia, whether from sport, an uneven footpath, or just an awkward step. If you've rolled your ankle once, you're at real risk of doing it again: research shows around 40% of people who sprain an ankle go on to develop chronic ankle instability, where the joint keeps giving way. So does bracing actually help, or is it just peace of mind?

The evidence is genuinely strong here

Unlike some joint supports, ankle bracing has robust research behind it. Multiple systematic reviews and meta-analyses have found ankle braces effective for both first-time sprain prevention and stopping repeat sprains in people with existing instability. Researchers believe this works through two mechanisms: the physical stability of the brace itself, and improved proprioception, essentially better communication between your ankle and brain about joint position, which helps you react faster to prevent a roll.

Why chronic instability matters

If your ankle regularly feels unstable or gives way, that's chronic ankle instability, and it's not just an inconvenience. Left unaddressed, it's linked to a higher risk of ankle arthritis, often a decade earlier than knee or hip arthritis typically develops. This makes ongoing support more than a comfort measure, it's a genuine preventive step.

How rigid should your brace be?

Not all ankle support is the same. Softer, compression-style braces (like a wrap or sleeve) suit mild instability or preventive wear during activity. More rigid braces with structured support suit moderate sprains or higher-risk activity. Whatever the type, research is clear on one thing: a brace only works if you actually wear it consistently, so comfort matters as much as design.

What to look for in an ankle support

• A heel-cupping design for a secure, supportive fit
• Breathable material that works under footwear
• Easy on-and-off closures so you'll actually use it
• Enough compression to feel supportive without cutting off circulation
