OverviewPro-Flex Pivot foot by Össur is a multi-blade prosthetic foot with a pivot mechanism that significantly increases ankle peak power and range of motion compared to conventional energy-storing-and-return (ESR) feet, enabling a more natural and powerful push-off without active components.
Product type- Multi-blade prosthetic foot with integrated pivot joint
- Designed as an advanced ESR-style foot to enhance ankle mechanics
Intended use- Lower-limb prosthetic foot for transtibial and transfemoral amputees requiring improved ankle power and range of motion during daily and variable-pace activities
Key benefits- ~95% increase in peak ankle power vs conventional ESR foot
- ~82% increase in ankle range of motion vs conventional ESR foot
- Reduces load on the contralateral limb (reported reductions in knee varus moment and contralateral loading)
- Lightweight cosmetic cover with slip-resistant sole for barefoot stability on wet/slippery surfaces
- Compatible with a wide range of footwear and easy to maintain
