The ultra sticky sole allows optimum use on slippery terrain and keeps grip on mud or scree thanks to the lugs. The Spyral Tongue(TM) combines the advantages of quick fitting shoes with a traditional tongue and the protective features of a shoe with an integrated gaiter that avoids contact with stones and mud while running.

The lacing system is integrated to the uppers through the FusionGate(TM) technology with high density reinforcements: this solution allows to regulate inner volumes and the level of adherence of the foot within the shoe for a more precise race and stability even on traverses.
