Tech approach shoes are an oxymoron. They must provide climbing precision and grip for climbing classic alpine routes and via ferratas or when scrambling off the beaten track on technical rocky terrain to reach the rock face. And, at the very same time, they must provide comfort and walkability all day long, as professional mountain guides know very well.
Sulfur is the new fast-moving approach shoe designed for mountain professionals and competent climbers, featuring the new AST - Adaptive Shape Technology.
