CastleFlexx is a stretching and strength tool designed to help athletes, fitness enthusiasts, or anyone with chronic pain improve flexibility, core strength and mobility. It targets the entire posterior chain of the lower limb by stretching the soft tissue of the toes, foot, calf and hamstrings to improve lower back pain, herniated discs, and even cure plantar fasciitis. It’s made using exclusively sustainable materials and no virgin plastic. Castleflexx was created around the desire to make “Prehab” easy and accessible, helping people to prevent injuries before they happen.
