WillowWood META Arc

The META Arc is a moderate-to-high activity carbon fibre prosthetic foot for K3 & K4 amputees.

An integrated, biomimetic ankle joint offers users unparalleled inversion and eversion range of motion. The META Arc gives the best of both worlds with a lightweight, dynamic spring frame returning greater than 95% energy, with a split keel for superior stability and ground compliance on various terrain.

The heel and keel sections of the foot merge into a one-piece construction that is free of secondary fasteners. This eliminates excess weight, bolts, and weakened attachment points. The polycentric ankle motion stabilises socket and joint forces caused by terrain and movement.

  • Polycentric ankle
  • Boltless, unibody carbon fibre design
  • Greater than 95% dynamic spring
  • Energy return
  • Split keel
  • Waterproof and corrosion resistant
