G2 Evo

The La Sportiva G2 Evo is a serious boot for serious cold, designed to keep your feet functional on the world's highest peaks or during technical winter climbing endeavors. This is an evolution of La Sportiva's popular G2 SM, retaining the double-boot construction essential for extreme cold but refining aspects for improved performance. The outer boot integrates a Cordura gaiter, insulated with a waterproof, breathable membrane, and a heat-sealed zipper to fend off snow and ice. Inside, a removable, insulated inner boot provides critical warmth and allows for drying in a sleeping bag, a non-negotiable feature for multi-day expeditions.

While precise insulation values aren't published, the G2 Evo's combination of a robust gaiter, four-layer PE and EVA foam inner boot, and Air-injected rubber rand clearly targets environments down to -60°C. The construction emphasizes durability with materials like Cordura and a Vibram Matterhorn sole, reinforced with a low-profile tread for secure footing on mixed terrain and ice. The Boa closure system, present on both the inner and outer boots, is a standout feature, offering quick, precise adjustments even with bulky gloves, and crucially, it's easily field-reparable. The overall profile is remarkably trim for a double boot, aiding precision on technical ice and mixed routes.

This boot is a specialist, not a generalist. Its bulk and warmth are overkill for anything less than high-alpine expeditions or technical ice climbing in genuinely cold conditions. Compared to single-layer alpine boots, it's heavier and less nimble, but that trade-off is essential for its intended use. For those operating in the extreme cold where frozen feet are a real and constant threat, the G2 Evo provides a reliable, high-performance platform that builds on a proven lineage.
