La Sportiva Aequilibrium ST GTX Botas de montaña de mujer - Negro/Aqua - Talla 39.5

The La Sportiva Aequilibrium ST GTX stands apart from typical mountaineering boots by blending the precision of a technical alpine boot with the comfort of a trekking boot. Its semi-crampon compatible design and 3D Flex System Evo™ deliver a natural stride on approach while retaining the rigidity needed for glacier travel and via ferrata. The Double Heel™ construction enhances downhill braking, and the Vibram Matterhorn outsole with Impact Brake System grips confidently on mixed terrain.

Highlights

• Gore-Tex Performance Comfort lining for waterproof, breathable protection
• Water-repellent high tenacity nylon upper with honey-comb Guard™ reinforcements
• Semi-automatic crampon compatibility (B2) for technical routes
• Vibram Matterhorn outsole with Impact Brake System for secure footing
• 3D Flex System Evo™ and Double Heel™ for efficient movement and braking

In daily use

Built for women, the Aequilibrium ST GTX offers an ergonomic, precise fit that reduces fatigue on long approaches and steep ascents. The traditional lacing system allows fine-tuned adjustment, while the rubber shell midsole provides the stiffness required for front-pointing on hard snow or ice. At 1.26 kg per pair, it balances weight and performance for technical mountaineering, heavy backpacking, and glacier travel.
