The Runner is characterized by a durable and lightweight carbon spring providing the athlete not only with a powerful drive, but with stable turning characteristics. The dynamics and spring stiffness of the Runner are adaptable according to individual requirements by shifting the adapter alongside the carbon spring.  This has no effect on the basic alignment.

  • Anterior positioning of the adapter for relaxed running and comfort due to an increased spring deflection.
  • Posterior positioning of the adapter for powerful running due to an increased forward propulsion.
