Prosthetic Feet


Combining an incredible 27° ankle motion and significantly greater ankle power than a conventional carbon fiber foot, Pro-Flex has been developed specifically to enhance protection of the sound side. It closely mimics regular biomechanics, delivering a proven 11% reduction in load on the contralateral limb.

  • 27° ankle motion
  • Exceptional energy return
  • Innovative pivot mechanism
  • Aesthetically pleasing, anatomical footcover

Össur recommends using Pro-Flex in conjunction with the sleeveless vacuum suspension system Unity®, which adds minimal weight and no extra build height, and does not interfere with Pro-Flex dynamics. Unity is designed to provide secure suspension in combination with Iceross Seal-In® technology, while stabilizing volume fluctuations and maintaining comfortable socket fit throughout the day.
