Maintain Healthy Movement

Designed to provide compression, support, & stability.

DASS is an innovative solution to ankle pain and instability that can give patients the freedom to stay active. The flexible design provides compression, support, and stability to help protect against ankle sprains, eversion and inversion injuries, and aid in healing by preventing reinjury. Offering the benefits of a custom orthotic brace, DASS is a compression sock and ankle brace in one with a low-profile design that easily fits most shoes without compromising functionality.

Compression sock base: Knit engineered sock base offers mild graduated compression while providing arch support, assistance with proper foot alignment, and heel stability


DASS has a sleek compression sock base designed to offer graduated compression that supports the arch, promotes blood flow, and helps reduce swelling. Its low-profile design fits easily into most shoes without compromising fit or functionality.

Ankle support cage: Soft materials wrap around the foot to allow for dynamic stretch and flexible movement while protecting and supporting ligaments


The ankle support cage helps align the ankle and provides the support and flexibility needed to allow for more safe, natural movement. Patients enjoy a healthy range of motion and anatomically correct positioning while being protected from injuries like inversion or eversion sprains.

Ankle Stability Straps: Soft straps wrap across the ankle to provide stability control and customized tension for the perfect fit.


Soft ankle stability straps hug the foot and ankle for customized tension and a perfect fit. Positioned to prevent injury and improve overall ankle stability, the straps provide the perfect blend of flexibility and resistance on all sides. The design is similar to figure 8 ankle taping without the hassle.

What Makes DASS Different?

Because DASS is both a sock and an orthotic ankle brace, it can be worn inside normal shoes while providing the same amount of support and protection. Lightweight and flexible, DASS locks the ankle into place and integrates the effect of taping or wrapping with straps anchored at the ankle, allowing for safe, healthy motion and restricting only unwanted movement.
