a superb brace in all regards [SEP] i bought this brace after a fall in which i would injured my knee as well as my ankle and needed to keep my knee completely immobile no lateral tuning or twisting at all and restricted flexing and extension it was the third brace i ordered the first was not nearly strong enough and the second sizing was off i am so glad i found this one before i ordered i measured my thigh knee and calf i was on the cusp between sizes and so ordered up that seemed like a good idea at the time because it allowed me to wear the brace over my slacks as well as under but after almost a month of continuous wear the thigh which was a little larger than i needed to begin with seemed to have stretched out i could not wrap the upper portion tightly enough and even with the straps cinched tightly the brace slipped after an hour or two or wear i wrote the seller and asked if there was a solution this brace was costly enough that i did not want to have to pay out of pocket for a second one and they offered to send me a smaller size it arrived within a few days accompanied by a label for free return of the first i could not have been more impressed or more grateful i would recommend this brace and this seller to anyone
