WOW! It stays put!

Only regret is I didn’t order this sooner! I have a few drugstore knee braces and they all end up sliding down my leg and don’t offer great support. I have been thrilled with OS1st’s plantar fascitis socks so I thought I’d try your knee brace and it is worth every penny.

Knee Brace

Nice, firm, yet comfortable brace. Recommend it

Works good

It's seems a little tighter than I would expect, and I did measure and make sure I ordered the right size. It offers really good support, a and I love that I can adjust it so it stays where I want it.

Good fit, easy to put on

I found the braces fit pretty well, snug without pinching. They were able to slide on with no issues. I liked the support ribs, they were firm without being intrusive.

Works

My husband has a weak right knee. He really likes this brace. It fits snugly and gives him very good support without being uncomfortable. He has tried elastic knee sleeves before, but this gives him even more support. especially with the patella stabilizer. It is comfortable to wear for long periods of time, it fits true to size, and it's slim enough to wear under pants.
