Running foot 1E90 and sports knee module 3s80 Used

The Ottobock 1E90 Sprinter is a high-performance carbon fiber running foot designed for transfemoral and transtibial amputees participating in track, sprinting, or field events. Lightweight and extremely responsive, the 1E90 uses a C-shaped curved design that stores and releases energy efficiently, mimicking the spring-like action of a natural foot during high-impact running. Its stiffness and energy return can be fine-tuned for individual users based on body weight and activity level, making it suitable for competitive and recreational athletes alike. The open design also minimizes dirt buildup and allows for easy cleaning—ideal for outdoor environments. Whether on the track or trail, the 1E90 delivers propulsion, ground compliance, and stability for top-speed performance.

Paired with the 1E90, the Ottobock 3S80 Sports Knee is a mechanical, single-axis knee joint engineered specifically for running and high-intensity sports. It features a special rotary hydraulic unit that provides increased resistance during swing and stance phases, allowing for smooth and controlled leg movement at high speeds. With its preflexed shape and lightweight aluminum construction, the 3S80 offers dynamic knee flexion and extension for a more natural stride while running. Designed to complement the 1E90, the 3S80 allows athletes with above-knee amputations to accelerate, decelerate, and maneuver with greater control and confidence on a variety of terrains. Together, this system is optimized for serious sport performance, offering a reliable solution for athletic prosthetic users aiming for power and speed.
