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.

FAQS

Answers for you

The Triton side flex prosthetic foot with side-to-side flexibility was designed for highly active individuals (mobility grades 3–4) who navigate varied indoor and outdoor environments and place a high value on uncompromised response and control – even when performing high-impact activities. It is suitable for users weighing up to 125 kg. Due to its low height, the Triton side flex is also suitable for users who only have limited build height available for the installation of their prosthetic foot. Both transfemoral and transtibial amputees can benefit from the advantages of this prosthetic foot.
