La Sportiva Aequilibrium Trek GTX Men's Trekking Boots Savana/Carbon Size 43

Technical trekking footwear rarely balances agility and protection as effectively as the Aequilibrium Trek GTX. La Sportiva merges the lively feel of a mountain running shoe with the sturdy support of a traditional backpacking boot, stripping away bulk while keeping a high-cut collar, full protective rand, and waterproof-breathable GORE-TEX Extended Comfort lining. The result is a boot that moves quickly on approaches, grips confidently on rocky traverses, and stays stable under heavy loads.

Highlights

• GORE-TEX Extended Comfort waterproof-breathable membrane
• Vibram® SpringLug Tech outsole with Impact Brake System™ for confident descents
• 3D Flex System Evo™ ankle support for natural articulation
• PU-Tech Lite™ rand and Honey-Comb Guard™ reinforcements for abrasion resistance
• Semi-automatic crampon compatibility (B2 rated) for light mountaineering
• Ergonomic 5mm footbed and dual-density PU foam midsole with TPU inserts

In daily use

On technical terrain, precision and shock absorption matter equally. The SpringLug Tech outsole uses angled lugs and a rounded heel to reduce impact forces, while the Impact Brake System™ increases braking power by up to 20% on steep downhills. The high-cut collar with 3D Flex System Evo™ wraps the ankle without restricting forward motion, so you can move quickly through scree or talus. Inside, the Ergonomic footbed supports the arch and heel, and the GORE-TEX lining manages moisture during high-output efforts.
