If you are a runner, you know how debilitating knee pain can be. The Zamst RK-1 Plus knee brace is specifically designed to prevent iliotibial band syndrome (ITBS) and relieve pain on the inner sides of the knees. Thanks to its spiral strap, it realigns your leg and limits the friction of the iliotibial band on the outer side of the knee, thus relieving pain. The lightweight resin springs gently stabilize the knee without hindering movement, while the thin and breathable fabric with a water-repellent surface keeps your knee cool and dry during the run. The knee brace features a unique function: the spiral elastics rotate and lift the lower leg, while the uniquely shaped inner film maintains the lower knee joint in proper alignment and relieves stress on the outside of the knee. The RK-1 Plus benefits from an innovative textile design, ultra-lightweight and extremely comfortable, with adjustable compression and breathable materials. Its unique three-dimensional cut (patented) adapts to the movement of runners.
