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. This function minimizes irritating, compensating movements by reducing the sideward tilting placed on the knee or in the socket. 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.

Triton side flex – adaptable with socket stability

Adapts effortlessly to sideward slopes

There was a time when Marije would have taken detours. Now, thanks to her Triton side flex, she no longer avoids sloping sidewalks or slanted curbs.

Marije and her boyfriend stand in the bow of a tourist boat, taking selfies with a smartphone.
Standing safely on unsteady surfaces

A boat tour through Amsterdam: what a great surprise from her boyfriend! These carefree images show that Marije’s prosthetic foot helps her feel secure and worry-free even on unsteady surfaces.

Marije skilfully navigates the confined space between the furniture in her kitchen with her Triton side flex carbon foot.
Moving in confined spaces

A quick movement between the sink and fridge, a small step to the side towards the cutlery drawer. Thanks to her Triton side flex, Marije can prepare a meal in a hurry when she has to – before her next shift at the hospital.

Marije leans to the side against her fridge with her Triton side flex prosthetic foot as she talks to her boyfriend.
Relaxed leaning and standing

With her previous prosthetic foot, Marije used to find it very uncomfortable to simply lean sideways against a wall or door frame while chatting with friends. But the side-to-side flexibility of her Triton side flex lets her stand in a relaxed position, even during longer conversations.

Marije carries her bicycle out of the corridor and down some steps into the courtyard with her Triton side flex prosthetic foot.
Safe and comfortable movement

Thanks to her Triton side flex, everyday activities like quickly moving the bicycle down the steps from the hallway or carrying the weekly shopping up to the apartment do not represent a challenge for Marije.

Standing with her legs wide apart, Marije playfully swings a young patient around by her hands in a treatment room.
Standing with legs apart: safe and comfortable

As a pediatrician, Marije is always concerned about the well-being of her patients. Her Triton side flex gives her stability she can count on when lifting and carrying the little ones.

Walking on uneven ground and obstacles

Thanks to her Triton side flex prosthetic foot, which easily compensates for side-to-side unevenness and small obstacles, Marije is now able to dedicate her full attention to her surroundings and the people around her when she takes walks outside.

Marije and her boyfriend sit on the edge of a fountain and let their legs dangle in the water.
Afraid of water? Not with the Triton side flex!

The Triton side flex is resistant to fresh, salt, and chlorine water so Marije can confidently spend time in and on the water when the weather is hot.

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.

Are you very active and on your feet from morning to night? The Triton Harmony is a prosthetic foot with an integrated vacuum system that helps compensate for the fluctuations in volume that occur in the course of the day, giving you a firm hold in your prosthesis from morning to night without putting strain on your residual limb or skin. The secure connection between the residual limb and leg lets you control your prosthesis more effectively. The firm fit also means there is less play between your residual limb and the socket, which can reduce skin irritation. It supports the natural way your leg rotates as it moves, ensuring you can move comfortably despite the firm fit – without feeling strain due to torsion in the socket. This boosts your comfort in your demanding daily routine.
