Description:Scarpa Maestrale 4.0 Black/Orange – Alpine Touring Boots
The Maestrale 4.0 is a time-tested bestseller that stands out with its bold design and, most importantly, its outstanding performance. It’s a reliable, intuitive, and comfortable ski touring boot that makes any terrain ideal for winter adventures.
The 4.0 version is refined for even greater ease of use and is suitable for ski tourers of all skill levels.
Its overall shell and cuff design delivers excellent stiffness while maintaining a low weight. The updated SPEED LOCK XT ski/walk mechanism allows smoother and more effective mode switching, with the added benefit of adjustable forward lean to suit each skier’s preference.
A cuff rotation range of 60° allows long, energy-saving strides on flat terrain and maximizes glide efficiency.
The shell and tongue are made from Pebax® Rnew, a renewable material derived from castor oil. It maintains consistent flex even at low temperatures, preserving energy on both ascents and descents.
The Scarpa®/Vibram® sole made with TOP85 compound ensures excellent grip and durability. It complies with DIN ISO 9523 and is compatible with all TLT bindings.
The CROSS FIT PRO FLEX TOURING liner is heat-moldable, offers excellent insulation, and dries quickly. It includes laces for improved foot retention.
Three lightweight buckles—two with micro-adjustment—and a plastic instep strap keep the foot securely positioned during both climbs and descents.
