The Back on Track Performance Knee Brace is a new variant to the standard style. It’s tapered and elasticated and is an ideal choice for those engaged in sports activities. The fit moulds nicely to the wearer’s skin. Due to the weave of the material it has the ability to stretch in four different directions and thereby capable of maintaining its regular shape. Around the inside of the knee brace top is a rim of silicone to prevent slippage.
