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.

Adapter for the distal connection of the 1E91 Runner
4R218/4R216 Runner adapter

The pyramid adapter of the 4R218 connection adapter can be rotated to any position and makes it easier to adjust the prosthesis to suit the user. The adapter is also lightweight and robust. The 4R216 Runner adapter with 4 holes can be used as an alternative to the pyramid adapter.

Runner soles in two versions
2Z540 and 2Z541 sole types for the Runner

Two types of sole are available for the Runner. The Runner sole for recreational athletes is a classic all-rounder for terrain such as asphalt, gym floors and nature trails. In contrast, the Runner spike sole is primarily geared towards performance-oriented competitive runners due to its good traction on tartan tracks.

1E91 Runner carbon spring

The Runner is characterised by a resilient, lightweight carbon spring, which provides runners with a high level of propulsion and enhanced stability when turning corners. By moving the adapter along the carbon spring, the dynamic response and spring stiffness of the running prosthesis can be adapted to the individual needs of the user. The bench alignment of the prosthesis remains unchanged.
