Short Description

Proprio Foot is an adaptive microprocessor controlled ankle for low to moderately active amputees

Motor-powered ankle motion increases toe clearance in swing phase by raising the forefoot, reducing the risk of trips and falls

It also adjusts the ankle angle to changing terrain, providing enhanced gait quality on stairs and inclined surfaces

  • Increased toe clearance in swing
  • Automatic terrain adaptation on level-ground, ramps and stairs
  • Dynamic carbon foot blade with exceptional roll-over characteristics
  • Relax-mode for comfortable sitting and chair-exit-mode for easier sit transfers
  • Integrated battery
  • Weatherproof
  • Accompanying Össur Logic app for iOS devices provides: Simple practitioner setup and adjustments, and printable user activity reports, user adjustable ankle alignment for changing footwear and selection of user preferences and monitoring of step count and battery charge level

Proprio Foot02

Split toe

A split toe feature allows the foot to adjust to the surface below, allowing amputees to walk naturally on uneven ground. Also available in solid toe.

Proportional response

The layering of carbon fiber optimizes the deflection of the forefoot from mid-stance to toe-off and is proportional to the user’s weight and impact level.
