Convenience: No assembly required; simply adjust to your desired angle and step onto the calf stretcher. The built in timer lets you set your stretch duration. Adjustable angles: 18 incline positions for you to tailor the stretch to your needs, increasing muscle sensitivity during workouts and helping you achieve proper calf and Achilles stretches. Durable design: Made from PP, foam, and steel with a stable triangular base that resists wobble and deformation for reliable support. Portable and foldable: Lightweight and foldable for easy transport and storage; suitable for use at home, in the office, or outdoors. Use scenarios: After a run, use a gentle incline for 5 to 10 minutes to loosen calves and speed recovery. At work, take short breaks for quick calf stretches to promote mobility and reduce stiffness. While traveling or at the gym, fold and pack the wedge for use on carpet or mats to maintain ankle flexibility on the go.
