Athletes with transtibial or transfemoral limb loss who need to run or sprint commonly use energy-storing prosthetic feet. These feet are made from materials that store energy with each step and release it efficiently, helping the athlete move forward with greater power during walking or running.
For running and sprinting, carbon fibre foot blades have become essential. Their advanced design allows athletes with unilateral or bilateral limb loss to participate and compete in sports that were once not possible.
However, these blades have some limitations. Athletes who play on uneven ground and require natural movements like pronation and supination still rely on traditional mechanical ankle designs, which offer better stability and reduce the risk of falls or injuries.
Features of the Sprint Flex Carbon C-Blade for Runners and Sprinters: –
Ø High-performance, Carbon fibre prosthetic foot designed especially for runners and sprinter athletes.
Ø Its C curve shape is engineered to mimic the natural spring-like function of biological tendons, absorbing impact and efficiently returning energy to propel the runner forward.
Ø Energy Return –Store Kinetic energy as the runner lands and releases it during push-off, which significantly reduces the physical effort required to maintain speed and endurance.
Ø Shock Absorption and Energy Dissipation: The curved structure absorbs impact forces and efficiently dissipates energy, reducing strain on the residual limb and improving comfort.
Ø Optimised for Symmetry and Efficiency: The design promotes near-symmetric step lengths and efficient gait dynamics across various speeds, enabling smoother transitions from walking to sprinting.
Ø Lightweight and Strong –Made from high-strength, lightweight carbon fibre, the blade offers superior strength.
Ø Carbon fibre is resistant to stress, heat and deformation, making C-Blade a reliable option for demanding athletic activities.
Ø Material – Carbon and stainless Steel
Ø Weight -720g, Body weight – Up to 120kg
At Proactive Technical Orthopaedics Pvt. Ltd., Pune, we provide the SprintFlex Carbon C-Blade, a high-performance prosthetic foot designed specifically for runners and sprinters who seek speed, efficiency, and comfort.
