Flex-foot Assure

Flex-foot Assure

by Ossur

Flex-Foot Assure is the perfect solution for the diabetic and vascular amputee population. Flex-Foot Assure incorporates basic Flex-Foot® technology that allows for a soft, smooth roll over allowing for a stable gait with the benefits of dynamic response.

Building on the proven dynamics and energy return features of the original Flex-Foot, the Flex-Foot Assure is ideal as a first prosthesis or a more permanent option for the less active, particularly those experiencing poor vascular health and/or diabetes. Improvements in gait achieved with the Flex-Foot Assure have a direct and positive influence on health and the potential deterioration of the sound side.

Designed specifically for slower speed walkers, Flex-Foot Assure incorporates an active heel combined with the full length keel that work together to protect the vulnerable sound limb. The proven design and simple fit of Flex-Foot Assure allows basic ambulators to take advantage of premium technology just right for them.


  • Vertical forces generated at heel contact are stored and translated into a linear motion described as Active Tibial Progression.

  • Active Tibial Progression reduces the need to actively push the body forward using the contralateral foot and also equalizes stride length.

  • The full length keel/toe lever matches the length of the sound foot, providing improved support to the prosthetic limb during late stance. It ensures that users spend equal time on the prosthetic foot and natural limb, thus providing improved walking dynamics and reduced impact to the sound limb.

  • The layering of carbon fibre, optimised through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fibre heel and forefoot components are proportional to the user’s weight and impact level.
