Repetitive or long term squatting wears down the menisci in the knee, making it more susceptible to tearing. By limiting the range of knee flexion, the Knee Saver relieves stress on joints, tendons, and cartilage. Molded polyurethane foam with an integral skin for extreme durability. Uniquely notched on back to prevent slipping. Widely adjustable elastic straps with hook and loop closure ensure a comfortable, secure fit. One size fits all. Latex free.
