When you're tackling serious terrain, you need a seriously well-designed boot. This grippy and stable boot that lands at mid-height is built around a GoreTex Performance Comfort lining to ensure a pleasant temperature at altitude all year round. The Mammut Pacific Crest GTX boot's simple appearance hides a range of technical surprises: Integrated Motion Control provides lateral support without restricting forward and rear flexibility; FeetMap and Memo Foam offer an optimal fit, cushioning and temperature; and the Rolling Concept promotes natural rolling, support and cushioning. Mammut's PD Cage sole cushions and distributes energy generated in the heel area, while still ensuring the required precision. It also supports the inside of the foot arch. The all-round rubber rand provides protection from rocks and boulders. * Main product photo is Graphite/Cyan.
