Review on ACE Adjustable Knee Brace: Dual Stabilizers for Weak, Injured, Arthritic or Sore Knee by Steven Bush

If the inner sleeve is too small/tight, you should not put your foot through it. I never do and they work fine. It's true that Velcro tends to wear out. Sometimes I wrap them with duct tape after the velcro starts to come loose. Or just order new ones. I wear them on both knees every day, all day, and it usually takes about 4 months before I notice the velcro slipping off. For the comfort and pain relief they provide I don't mind spending the money if they need to be replaced.
