Physiological rollover at all walking speeds

The lightweight carbon construction of the Trias combined with its dual spring elements provides elastic shock absorption for the user at heel strike.

  • The rollover of the prosthetic foot is largely physiological and it also scores points with its energy return while walking.
  • The Trias makes controlled movement patterns possible.
  • Switching between various walking speeds is effortless for the user.
  • Strain on the sound limb is relieved.
  • The foot provides users with controlled support on uneven terrain.
  • Suitable footshells, which can be easily exchanged by the user, are available in two versions (slim, normal).
