I've been dealing with knee problems for several years, but I need to keep active and do a lot of walking and running because of my job. So I needed a brace that's both supportive and comfortable and work and at the gym.
This one fits the bill, as it feel good over skin or over a liner/sock. It's very supportive and adjustable, and allows for a good range of motion so I can go from sitting to running without having to adjust it every time.
I also like to materials and the design -- the blue and black looks slick and the materials are smooth against my skin. Plus, none of the seams or velcro straps dig into my skin.
Highly recommended.
