NATURE IS THE TRUE ENGINEER
EVERY STEP STEADY, EVERY LANDING SOFT

PROTEOR rethinks the K2 solution from nature's blueprint:

  • Plantar springs anchor stability and absorb vertical load for socket comfort.
  • The toe joint mirrors the MTP joint.
  • The e-TPU heel cushions every landing.

Steadiness and comfort, by design.

 

Why this foot (USPs)

Stability & balance: Plantar springs load and release with every step, anchoring stability and balance whether the patient is standing, walking, or navigating uneven ground.

Step cushion: Less impact on the residual limb, so the patient can focus on living – up to 20mm of shock absorption at the heel, 13mm of vertical load absorption.

Terrain adaptability: The foot conforms to uneven surfaces, so the patient moves with confidence on any terrain. More than 8° of inversion/eversion and 20° toe extension make it possible.

EXONEO CORE was designed for low activity users for whom every step is a decision. These are patients who prioritize stability, balance and comfort over speed. Patients who feel every impact in the residual limb throughout the day. Patients who want to move through their home, their neighborhood, a slope, or an uneven sidewalk without thinking about their foot.

EXONEO CORE was built for exactly that.

Every step the human foot takes follows the same sequence. Exoneo Core replicates it, phase by phase, every component mirroring its counterpart in the human foot.

Phase 1: Heel strike
The e-TPU heel replicates the heel fat pad, compressing on contact to absorb the initial shock. Every step starts with comfort.

Phase 2: Flat foot
The plantar springs replicate the plantar muscles, distributing load across the full footprint, absorbing vertical load and anchoring stability as weight shifts naturally from rear to front.

Phase 3: Heel lift & toe extension
The toe joint replicates the metatarsophalangeal joint: As the heel rises, the toe joint extends up to 20° while maintaining full ground contact, stabilizing the end of the step. Energy stores in the plantar springs and the fiberglass composite.

Phase 4: Propulsion
The stored energy releases, propelling the body forward and preparing the next step.

Four phases. One continuous motion. Exactly as nature designed it.
