Proteor Sierra FS1 foot prosthesis (France)

Product description

Carbon prosthetic foot with high flexibility, smooth gait, stability on uneven surfaces, and efficient energy return for users with a moderate activity level. Proteor Sierra FS1 is a carbon prosthetic foot with energy return, designed to provide maximum smoothness, softness, and stability in everyday life. The special design with an angled top increases the functional length of the carbon spring, allowing it to store more kinetic energy during stance and effectively return it during push-off. Thanks to the split keel and full-size heel, the Sierra FS1 foot quickly contacts the surface with its entire area and easily adapts to terrain irregularities, ensuring the user feels confident and experiences a natural rollover with every step. Features of the Proteor Sierra FS1 foot Angle-Top design for enhanced energy return The angled cut of the upper part of the design increases the working length of the carbon spring element. This promotes increased energy storage during the stance phase and powerful return during push-off, making walking easier and less tiring. Split keel for excellent inversion and eversion The keel's longitudinal split design allows natural inward and outward foot movements (adaptation to lateral slopes). This ensures stability on uneven terrain, soil, or potholes, protecting the user from tripping. Full-size heel for early contact and stability The full-length heel ensures early achievement of full foot contact with the ground (foot flat) during the gait cycle. This creates a reliable support base, improves balance, and guarantees an exceptionally smooth heel-to-toe rollover. Resistance to moisture and all weather conditions The foot is designed for active use in any weather conditions — it is resistant to splashes and accidental short-term water immersion, making it practical for everyday life. Sandal Toe option The availability of a version with a separated big toe allows the user to freely wear summer shoes, sandals, or flip-flops.
