Ultimate Flexibility

The Sierra® prosthetic foot incorporates a long carbon fiber spring to provide users a smooth gait over a broad spectrum of activities. The split toe design provides excellent inversion-eversion so that amputees can walk with confidence on uneven terrain. A full length heel enables foot flat early in the gait cycle, providing a compliant foot with a stable base of support. The result is a product that allows amputees to walk comfortably with confidence.
