Product Description 1. Safely stretch and increase flexibility in your foot, ankle, and calf with the Adjustable Foot Rocker. The fluid rocking motion of the calf stretcher gently and evenly stretches your foot and calf to relieve pain, improve circulation, and reduce fatigue, injury, and muscle tension. 2. Reduce Foot and Heel Pain: Effectively reducing pain from plantar fasciitis, Achilles tendonitis, ankle strain, arch pain, and other painful conditions, the Adjustable Foot Rocker facilitates a deep stretch of ligaments, tendons, and muscles. By increasing range of motion and flexibility, the safe stretches also minimize discomfort in the heel, legs, and back. 3. Safe for use on flat surfaces, including hardwood and tile floors, the base of the Adjustable Foot Rocker is lined with non-slip foam. The foam padding ensures the foot rocker stays in place without slipping. 4. Ergonomic Foot Plate: An angled foot plate to ensure proper foot position for safe and effective stretching and a space in the midfoot to strengthen the ankle as well.
