Capezio H21U Arch is a seamless and flexible silicone band that provides essential support and stability while dancing. Reduces over-stretching of the plantar fascia and Achilles and can help improve pointe work. Supports good body posture and alignment. Arch can be worn barefoot or in combination with Capezio Extend or other shoes. When starting out, wear Arch for 30 minutes per session only and gradually increase the wear time to 2 hours.
