The forefoot and heel are constructed from a lightweight, soft carbon fiber composite material joined together by a base spring made of high-performance polyester, creating a cohesive system. This allows for particularly smooth transitions. One of the benefits of the Rhine S600's split forefoot area is that it adapts easily to a variety of surfaces, helping to ensure control of the user's movements. This provides excellent traction when walking on uneven surfaces or changing direction quickly, such as during sports. The Rhine S600 is intended for patients who wish to use a dynamic carbon fiber prosthetic foot for everyday life and recreational sports.
