This brace is great! It fits tight enough to provide proper compression without cutting off circulation. It is also breathable; the brace didn't make me sweat too much or overheat. Although my training was not ideal due to nagging knee pain, the CEP knee brace got me through the Army 10 Miler comfortably. The no-slip bands also did their job - the brace did not budge one inch during the race! I would recommend this product to anyone with chronic knee pain that is looking for a long-term solution!
