Triton side flex

The Triton side flex was designed for highly active users who navigate varied indoor and outdoor environments and place a high value on uncompromised response and control even when performing high-impact activities.

What would life be like without surprises? The prosthetic foot features a unique degree of side-to-side flexibility and secure, full-surface ground contact – also on uneven surfaces. The function module reduces the sideward tilting moments placed on the knee or in the socket, which are often perceived as irritating, and minimises compensating movements. You can finally concentrate on what’s important to you and the people around you – because now you can decide where to go.

  • Lateral adaptation for an enhanced feeling of safety
  • Powerful, dynamic rollover
  • High energy return
  • Supports agile and high-impact movements

It's more than a prosthetic foot. It's a foundation.

Stop bumpers

Stop bumpers gently dampen the side-to-side impact when the full range of motion needs to be utilised on very uneven ground or slopes.

Proven Triton platform

The familiar properties of the Triton platform are not affected by the side-to-side flexibility and ensure the prosthesis is as dynamic as it needs to be.

Innovative ankle unit for mediolateral flexibility

The effortless mediolateral flexibility is achieved by a titanium torsion bar. This technology permits a 20° range of motion (10° medial and 10° lateral).

Robust titanium adapter

Thanks to integrated seals and the use of corrosion-resistant materials, the mechanism is protected against fresh, salt and chlorinated water.

User Experience

Triton makes the difference

Marije

Marije is a vibrant young woman who is always on the go – at her job, during her free time in the park or with a boat on Amsterdam’s canals. Thanks to her new Triton side flex prosthetic foot and its unique side-to-side adaptability, Marije goes her own way without needing to think about where she puts her foot next.

Functionality

More lateral flexibility, more secure ground contact

New lateral flexibility

Conventional prosthetic feet adapt to lateral slopes only to a small extent at heel strike. Only later on do these feet adapt to a greater extent as the load on the forefoot increases, with maximum adaptation occurring at the end of the stance phase. The Triton side flex adapts to lateral slopes and uneven ground to a high degree right after heel strike. This has a positive impact on the user’s comfort and safety.
