LET'S FACE IT. WHEN YOU SLAM YOUR KNEE TO THE GROUND, IT HURTS. Unlike any other kneepad, Patella Digs incorporate a unique impact protection system. Thousands of shock-absorbing beads absorb and redirect impact away from your knee. Plus, the beads enhance airflow for maximum circulation and cooling. Frontal patella protection is provided with not one, but three impact absorbing layers for maximum protection. The Patella Digs' unique "sliding patella track" is designed to fully protect the patella bone-even if the kneepad slips a little bit. Athletes often hit and hurt the sides of their knees. Injury to these side areas, called the femoral condyles and the tibial plateau can cause swelling and lingering pain. Patella Digs are designed with two, specially shaped condyle pads to protect this tender area. Ever get a sharp pain right at the bottom of your kneecap? Known as Osgood-Schlatter's disease, this pain comes from inflamation of the patella tendon. Patella Digs add a special pad around the tibial tuberocity, dispersing contact pressure to other areas.
