Designed for ski mountaineers who prioritize uphill performance without sacrificing stiffness or precision on the descent, the Dalbello Quantum EVO Sport AT optimize every gram by eliminating the superfluous weight of conventional touring boots.

Bonded Shell: Maximum Torsional Stiffness with Minimum Weight

Their structure uses patented Bonded Shell technology, composed of two independent anatomical halves molecularly fused together. This construction with reinforced technical polyamide makes it possible to minimize wall thickness in neutral areas and concentrate stiffness in the structural and lateral ribs. The result is extremely low weight on the ascent and excellent torsional stiffness for confidently driving edges on hard snow or exposed sections.

Ski/en/?controller=category EVO Dual Link Mechanism with 65° Range

The EVO Dual Link system releases the cuff, offering a 65° range of motion in walk mode (Walk), eliminating mechanical friction to allow a natural, broad and relaxed stride on long approaches. With a single movement of the rear lever, the cuff is firmly anchored to the shell with an anatomical forward lean, instantly transforming into a solid and responsive boot for descending.

FreeBuckle Cable Closure and 99 mm Touring Last

Instep and cuff adjustment is achieved through the cable-guided FreeBuckle system, which distributes tension progressively and evenly around the entire foot without creating excessive pressure points or restricting circulation. Its 99 mm last provides the optimal volume to hold the heel firmly in place while maintaining comfort and thermal insulation during outings lasting several hours.

Heat-Moldable ID EVO Sport Liner and Vibram Touring Sole

It comes equipped with the ultralight ID EVO Sport liner, fully heat-moldable and customizable to the shape of each foot, with pre-shaped elastic zones at the ankle to prevent rubbing on the ascent. The full-length Vibram® Dual Density rubber sole (Touring 9523 standard with certified metal Tech inserts) ensures firm grip on icy snow, rock or mixed ridgelines, guaranteeing secure steps during any transition.
