The sport foot for relaxed running and powerful sprints

The Runner prosthetic foot is the perfect companion for athletic, active users. Thanks to its ease of use, it is also suitable for less experienced runners. At the same time, it offers excellent performance for professional athletes.

  • In addition to a high level of propulsion, the high-performance carbon spring offers excellent energy return and enhanced stability when turning corners.
  • By shifting the adapter along the carbon spring, the dynamic response and spring stiffness can be adapted to the individual needs of the user – without changing the bench alignment of the prosthesis.
  • The connection adapter, which features a pyramid adapter that can be rotated to any position, is easy to use.
  • Both trial and definitive fittings are especially straightforward thanks to flexible adjustment possibilities and the connection to the modular prosthesis solution.
