Ideal prosthetic components


The prosthetic feet from the Triton family of products are suitable for active users. They are made of a set of flexible carbon springs. This design allows the foot to function as a flexible unit, which creates a particularly smooth rollover. Notwithstanding the system's ability to move, the Triton feet provide a consistently high level of stability when walking and especially when standing. Furthermore, the foot's special structure ensures a powerful transition to the swing phase and a highly variable stride length. At the same time, the split forefoot section gives the user the necessary control to deal with uneven ground and quick changes of direction. The Triton is extremely well suited for meeting the requirements of an active lifestyle. Thanks to its outstanding dynamic response and flexibility, it supports a broad range of functions from everyday use to recreational sports.
