What Makes Our Ankle Brace Support Sock Different?

DASS is a stabilizing ankle brace and compression sock in one that delivers ultimate support, compression, and stability. Unlike traditional ankle braces, ours has a flexible design that is lightweight, breathable, and sleek so it can fit inside your shoe.

While the compression sock helps reduce swelling and improve blood flow, the flexible brace and stability straps allow for safe, healthy motion and restrict only unwanted movement. An effective ankle brace for sprains, strains, past injuries, and problems with stability, DASS uses PowerStep’s trusted support to get you moving with confidence.

Best Restorative Foot Support Device Ever

Best support device, yet, for relief of debilitating perineal tendosynovitis.

The design combines a compression sock, mid foot support cage, and crossover ankle straps. Can be worn all day.

Super comfortable, supportive, and restorative.

Feels Stable & I Can See It Working

I have fully torn three ligaments in my ankle and am a semi-pro athlete. I have chosen to see if I can get by without surgery and this brace has exceeded my hopes! I was given a 4-6 month recovery time and told my ankle will never be the same. I have recommended this to many of my athletes and coaches in my circles who have the same legacy of ankle injuries as I do. I can see it working to help stabilize my ankle while I am training. So grateful for this product.

Highly Recommend

I have sprained both ankles numerous times. Two years ago I fractured the left ankle, lower tibia. I have been wearing a very sturdy ankle braces since. I liked that these were socks but had the added support benefit. Wore them today playing pickleball. They felt good and provided great support. Highly recommend.

Great Brace Post Brostrom Procedure Surgery

This brace has let my daughter return to soccer without wearing a bulkier brace! She has much better ergonomics and form running. PT took her out of other brace and OK'd use of the PowerStep 13 weeks post surgery.

Have Never Seen Anything Like This

Love this, I rolled my ankle and tried some other braces - good support, but bulky and uncomfortable. Have never seen anything like this, good support, fits great in my shoes, and really comfortable - highly recommend.
