Triton smart ankle

Reclaim your choice.

You alone decide how varied you want your everyday life to be

With the Triton smart ankle, we are offering a prosthetic ankle joint which adapts not only to different walking speeds, but also to slopes, stairs and different heel heights. The Triton smart ankle is built around the proven carbon fibre spring, which stands for dynamic movement and is featured in all the feet in the Triton range. The combination of the carbon spring and mechatronic ankle joint enables you to live exactly the life you want thanks to the extensive range of motion it gives you.


The hydraulics control the ankle movement. The opening of the valve enables plantar flexion or dorsiflexion of the ankle (lifting and lowering of the foot).

Angle and acceleration sensors

These sensors make it possible to determine the angle of the ankle and its acceleration in space and provide important information to the microprocessor.

Force and moment sensor

The data required for ankle adjustment is provided by integrated technology called Europa which measures the forces and moments affecting the prosthesis.

Triton prosthetic foot module

The interaction of the three carbon fibre spring elements ensures a very smooth transition between the individual gait phases. The split forefoot section provides the safety and control needed to deal with uneven ground and quick changes in direction.


Integrated Bluetooth® technology enables straightforward communication with an iOS or Android-based smartphone.

Charging unit and operation

The prosthetic foot can be charged via a USB connection. Two buttons for manual operation as well as an optical LED status display are located directly above this.

Battery and electronics

The battery and electronics are protected inside the ankle joint. The integrated microprocessor coordinates all measurement and control processes, thus calculating the correct adaptation of the ankle joint to the respective type of ground and your individual gait pattern.

Advantages at a glance

Wide range of motion

Thanks to the moving ankle joint, the Triton smart ankle facilitates walking on ramps, slopes and stairs as well as at different walking speeds. With a range of motion of up 34°, it adapts to the respective type of ground with every step.

Relief when sitting and standing

When sitting or when standing on slopes, the Triton smart ankle can lower towards the ground. This not only creates a natural appearance, but also above all provides relief for your residual limb.

Heel height adaptation

No matter whether barefoot, flat soles or heels – thanks to the heel height adaptation, you can stand and walk in a balanced, stable way in any shoes. And at the touch of a button, too.

Operation via smartphone app

The Triton smart ankle can be operated easily and conveniently via smartphone app. An additional remote control is not needed. Besides the battery status and the heel height adaptation, the toe stiffness can be varied – to alter to a more relaxed or more dynamic walking style – or free ankle motion can be enabled. During this period, you can move your foot into any position you like, which particularly makes it easier to put on trousers.


The Triton smart ankle is built around the proven carbon fibre spring, which stands for dynamic movement and is featured in all the feet in the Triton range. Unlike its family members the Triton smart ankle has advanced microprocessor technology inside that controls all processes to facilitate user’s everyday life.

With every step the sensors of the foot provide data to the microprocessor to identify if an adaptation of the ankle angle is necessary. The resulting adaptations in plantar or dorsiflexion simplify walking on ramps or slopes, stairs and at different walking speeds. The adaptation occurs incrementally (step by step) to ensure smooth terrain transitions.

The moveable ankle enables:

  • Adaptation towards ramps, stairs and different gait speeds
  • Adaptation to shoes with different heel heights
  • Relief function while sitting or standing on inclines
