DESC: Our most popular knee support, GenuTrain is anatomically knitted for a precise fit and features an incorporated silicone insert. This comfortable, lightweight support relieves knee pain and swelling during sports or everyday activities. Product Features: An incorporated silicone insert leaves the patella pressure free and provides intermittent compression to the soft tissue of the joint leading to increased circulation, thus aiding in the resorption of swelling and edema. Promotes proprioception, thus heightening sensory awareness in the knee for increased joint stabilization. Graduated compression at the edges prevents constriction of circulation. Innovative knit in the popliteal region prevents bunching or pinching. Three dimensional knit with covered patella avoids window edema, yet keeps pressure off the knee cap. Medial and lateral stainless steel stays keep the support from rolling or bunching. Comfortable, lightweight, breathable knit will not retain heat and is machine washable
