Just like the HOJI PRO TOUR, the HOJI PU boasts not only the Dynafit-patented Speed Nose and Master Step inserts, but also a 3-buckle system. The significant difference is in the closure system: The HOJI PU does not come with the patented HOJI LOCK System, but with what we call the HOJI Single Lock System. That means the strap is not connected to the rear lever and thus must be latched separately to switch to downhill mode. An additional difference is in the materials: The HOJI PU is approximately 100g heavier than the HOJI PRO TOUR and has a slightly lower flex of 110. The HOJI PU features a last width of 103.5mm and is compatible with the Dynafit Cramp-in crampons.
