The Mini Foot Roller eases joint and muscle stiffness by providing pinpoint pressure to release trigger points and knots. This reduces chronic pain that is muscular in origin, decreases inflammation and increases mobility. Commonly used for plantar fasciitis, heel spurs, carpal tunnel syndrome, ulnar tunnel syndrome, trigger finger, tennis and golf elbow. Fantastic for runners, dancers, and workers on their feet all day. Made of highly durable and recyclable plastic (100% polyethylene).
