A support dedicated to the Achilles tendon that has never existed before. Firmly support the Achilles tendon by enhancing stability of the tendon and the heel.
Product Description

Stabilize around the Achilles tendon
The Achilles tendon pads, gently support and wrap around the Achilles tendon, increase stability of the Achilles tendon.

Stabilize heel and reduce stress on the Achilles tendon
The outer strap with taping function (heel lock) enhances heel stability. Stabilizing the heel at the insertion of the Achilles tendon attachment reduces stress on the Achilles tendon.

Suppress ankle dorsiflexion
Suppresses ankle dorsiflexion where the Achilles tendon is stretched by applying non-elastic materials on the outer strap with the taping function (dorsiflexsion suppression).

Three-dimensional cutting to fit in motion
As soft and cushioned material is used on the Achilles tendon area, the Achilles tendon is gently supported. Three-dimensional cutting helps realize good fit.

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 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 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.
