The Empower is an innovation in the field of prosthetic feet. It is equipped with an active ankle joint, making it the only prosthetic foot with powered propulsion.

Only the Empower continues to offer the combination of power, control, and stability:

  • Emulates the function and power of lost muscles and tendons 1,2
  • Provides energy instead of taking it away – even up ramps, hills and stairs 1,6
  • Life-like ankle movement that normalizes userʼs walking gait 4
  • Reduces joint forces which may result in less pain and fewer long-term orthopedic problems 1,2,5,6
  • Adjusts ankle power, resistance, and flexion in real time
  • Provides balance on variable terrain 3
