Thanks to its particularly grippy sole and the climbing zone in the toe area, which are suitable for use on the wall, this model is particularly suitable for technical approaches and via ferratas.
Shaft in chamois leather with all-round rubber protective rand for maximum protection against wear and tear during the climbing phase. Patented lacing system derived from the Mythos climbing shoe project. Both the fit and the lacing system are asymmetrical. Sole in Vibram of new concept: design to improve grip in the climbing phase and Impact Brake System for more grip on the descent. Insert in soft Eva 2 mm with anti-shock properties.
