It is similar to the running blade worn by Paralympic, Jonnie Peacock (CD.151-2016) which is also in the collection, although this objects consists of just the blade. It is designed for leg amputee athletes to enhance their performance in short distance sprints.\n\r\nThe blades are made from a carbon-fibre-reinforced polymer which makes the blades strong and light. More specifically, reinforced sheets of epoxy material are cut into square sheets and pressed onto a form to produce the final shape. The final product is highly flexible, which is important for the runner, as it allows the blade to store energy, giving the runner a stronger push off. Running performance is also aided by a long flat toe, and an angled positioning of the blade, which puts the runner in a forward-leaning position.\n\r\nÖssur are the current manufacturers of the Cheetah series of prosthetics. The original Flex-Foot Cheetah, however, was designed and released by the inventor Van Phillips in 1984. Phillips was an amputee himself, having lost a leg below the knee in a waterskiing accident at the age of 21. After the accident, Phillips was inspired to enroll in a programme for prosthetic design at Northwestern University. In 1981, he went on to work at the Center for Biomedical Design at the University of Utah in Salt Lake City and in 1983 he co-founded Flex-Foot as a company with Dale Abildskov, Bob Barisford and Walt Jones. Phillips created hundreds of prototypes for the Flex-Foot, many of which broke, before coming up with the final design. Philips took his inspiration from the C-shape of a cheetah’s hind legs which is where the design gets its name.\n\r\nIn 2000, he sold Flex-Foot Cheetah to Össur, an Icelandic company that develops, manufactures, and sells non-invasive orthopaedic equipment. Phillips’ original Flex-Foot blade design, with some variation, is now used by approximately ninety percent of Paralympian runners, and by others who can now enjoy more active lives as a result of his work.\n","physicalDescription":"A running blade made from carbon-fibre reinforced polymer in black with yellow strips on the sides and the Ossur logo in the centre of the blade.
