Ossur Flex-Foot Cheetah

  • Proportional response: 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.

  • Waterproof: Whether it's fresh water, salt water or chlorinated water, Waterproof Össur products will give you the maximum protection you need. First-rate materials provide permanent protection against harmful water ingress, even after submersion, whilst continuing to provide the functionality you expect.

  • Weatherproof: A weatherproof device allows use in a wet and/or humid environment but does not allow submersion. Fresh water splashing against the enclosure from any direction shall have no harmful effect. Dry thoroughly after contact with fresh water. Fresh water: Includes tap water. Excludes salt and chlorinated water. For a weatherproof system, only weatherproof components must be selected.
