The Flex-Foot Cheetah is a prosthetic human foot replacement developed by biomedical engineer Van Phillips, who had lost a leg below the knee at age 21; the deficiencies of existing prostheses led him to invent this new prosthesis.

Cheetah is recommended for TT users engaging in long distance running and who do not have clearance for Flex-Run with Nike Sole. The layering of carbon fiber optimizes the deflection of the forefoot from mid-stance to toe-off and is proportional to the user’s weight and impact level.

Sep 6, 2012 · The Flex-Foot Cheetah works by storing and releasing energy within a carbon fibre sprinting foot, a prosthetic that mimics the reaction of the anatomical foot/ankle joint to allow amputees to run quickly and naturally.

Work hard, stay focused, and race to win with Össur’s range of prosthetic sports solutions and running blades, including Cheetah®, Flex-Foot Cheetah®, Flex-Run™, and more solutions for #LifeWithoutLimitations.

A Flex-Foot Cheetah running blade replaces the hinge of an ankle with the elastic compression of a carbon-fibre-reinforced polymer capable of storing kinetic energy from the user´s steps as potential energy and then releasing it, like a spring.

Feb 14, 2018 · The Flex-Foot Cheetah incorporates untraditional materials to solve a design problem that had vexed the medical field for years: finding a prosthetic solution that allows the user to live a normal, active lifestyle.

Oct 20, 2019 · The unique shape of the Cheetah allows the prosthetic to flex and bend to impersonate foot ligaments and musculature. Because of the C-shaped segment, the kinetic energy from the wearer’s steps distributes and provides for a vertical forward movement when the toe leaves the ground and propels the runner forward, simulating normal human gait.

Aug 3, 2012 · We’ve heard all about Pistorius, the South African sprinter born without fibulas, who wears prosthetics called Flex-Foot Cheetahs that allow him to compete not just with disabled runners, but...

The Cheetah is a custom-built, high performance carbon fibre foot designed primarily for sporting activities. This is the optimal sprinting foot for both transtibial and transfemoral amputees. It attaches posterior to the socket, making it agile, strong and a proven performer for professional athletes around the world.

Aug 13, 2018 · The carbon fiber based prosthetic known as the “Flex-Foot Cheetah” was developed by Van Phillips and launched in 1996. This running blade had the shape of a Cheetah’s hind leg and was made from a carbon fiber / graphite / epoxy composite.
