FAQ for this product
Most braces are machine washable. After washing, hang them to dry in the shade. Please avoid washing with light-colored items, as colors may fade or transfer to other fabrics. When washing with other clothes, use a laundry net to prevent fraying or streaking. *Hand washing is recommended for some products. Please refer to the instruction manual for specific details (instruction manuals are also available on each product page of the Zamst website).
First, ensure you have the correct size and follow the instructions in the manual for proper application. Be cautious not to tighten it too much, as excessive tightness can lead to congestion
If the size is borderline, we recommend the larger size.
From Dr. Evan This is a concern I hear frequently from athletes, but in most cases, the answer is no. Research generally shows that modern sports braces have minimal impact on athletic performance when properly fitted. In fact, some athletes perform better because they feel more confident and less concerned about reinjury. Many professional players such as Trae Young have worn ankle braces most of their career which has helped them stay on the court for more games. Confidence matters in sports. If an athlete trusts their body, they're often able to move more naturally and aggressively. The key is choosing a brace that provides the right amount of support without being overly bulky or restrictive. A properly selected brace should help support performance, not limit it.
From Dr. Evan Not necessarily. One of the biggest mistakes I see is athletes assuming they're fully recovered just because the pain has gone away. Pain is only one piece of the puzzle. Before I recommend discontinuing a brace, I want to see good strength, balance, confidence, and sport-specific movement. Can you jump, cut, sprint, and land without hesitation? That's what matters. Many athletes feel fine before their body is truly ready for the demands of competition. In most cases, I recommend gradually reducing brace use rather than stopping all at once. The goal is to make sure you're not only pain-free but also physically prepared to handle your sport safely.
From Dr. Evan Both can be effective, but they provide support in slightly different ways. Lace-up braces typically surround the ankle more completely and provide uniform compression and stability. Strap-based braces often use figure-eight support patterns that help control specific ankle movements associated with sprains. As a physical therapist, I don't believe one design is universally better than the other. The best brace is the one that fits well, feels comfortable, works with your footwear, and provides the level of support you need. Athlete preference, injury history, sport demands, and comfort all play a role when selecting the right brace. The most important part is how does the athlete feel with it on because if they have confidence with a brace they won’t second guess wearing it.
From Dr. Evan Basketball is one of the sports where I'm most likely to recommend an ankle brace. As a physical therapist, I've treated countless basketball players with ankle sprains, and we know that once you've sprained your ankle, your risk of doing it again goes up significantly. This is because once the ligaments have been stretched and become laxed this creates instability and likelihood of another ankle sprain. Between jumping, cutting, rebounding, and landing in crowded spaces, basketball creates a perfect environment for ankle injuries. A quality ankle brace can provide valuable support during those high-risk moments. That said, I never want athletes relying solely on a brace. Strong ankles, hips, good stability, proper landing mechanics, and consistent injury-prevention exercises remain the foundation for staying healthy throughout a long season.
From Dr. Evan From first-hand knowledge I have seen the impact of volleyball on ankle sprains. Because of how common jumping and impact landing is in volleyball ankles are largely at risk for sprains. Ankle bracing can be a reasonable preventive strategy, even for athletes who haven't been injured before. As a physical therapist, I've worked with many volleyball athletes who wear braces proactively throughout their season. Research suggests that ankle braces can reduce sprain risk and severity, particularly in sports involving frequent jumping and landing. Making sure you have the right comfort level with an ankle brace is important and should be at the top of the list when choosing an ankle brace to wear.
From Dr. Evan As a sports physical therapist, I don't believe everyone needs a brace. But there are situations where a brace can be a smart tool. If you had just had an acute injury such as an ankle sprain or knee sprain a brace is a great tool during the protection phase to reduce the risk of further injury and provide stability and comfort. In my clinic, I often see athletes wait until they've been injured multiple times before thinking about prevention. A brace can provide an extra layer of protection during high-risk activities while you're continuing to build strength, balance, and movement control. The goal isn't to rely on the brace—it's to use it strategically to help keep you healthy and performing at your best.
