An amputation doesn’t have to mean the end of an athletic career. Both Paralympic and recreational athletes with prostheses demonstrate this every day. Ottobock has developed a carbon sports foot especially for their needs which already has a proven track record at international and Paralympic competitions. The foot’s outstanding performance characteristics come thanks to the carbon spring, which provides high propulsion and low resistance. The Sprinter stands out for its low weight and is suitable for people with transfemoral as well as transtibial amputations.
