Aequilibrium LT GTX čierna/žltá | 44,5

At a mere 525 grams per boot (size 42 EU), the Aequilibrium LT GTX sets a new standard for lightweight technical footwear. Built for demanding alpine environments, this boot pairs a GORE-TEX Performance Comfort lining with a Vibram® SpringLug Tech outsole to deliver waterproof breathability and tenacious grip on rock, snow, and mixed terrain.

Overview

The La Sportiva Aequilibrium LT GTX is a semi-automatic crampon-compatible mountaineering boot engineered for technical ascents, via ferrata, and heavy backpacking. Its water-repellent high-tenacity fabric upper with honeycomb Guard™ and protective film shrugs off abrasion, while the PU foam midsole with external Protective Shell System™ balances stiffness and shock absorption. A hook-and-loop lacing system with integrated gaiter keeps debris out and fit secure.
