La Sportiva Aequilibrium Trek W. GTX Women's Trekking Boots Carbon/Malibu Blue Size 39.5

The Aequilibrium Trek W. GTX stands out with its 3D Flex System Evo™ ankle hinge, delivering natural stride efficiency on demanding multi-day hikes. Unlike rigid mountaineering boots, this women's-specific trekking boot combines a semi-automatic crampon-compatible heel with a medium-stiff flex for comfort over long distances.

Highlights

• GORE-TEX Extended Comfort waterproof membrane for all-weather protection
• Vibram® SpringLug Tech outsole with Impact Brake System for reliable grip
• High-cut ankle support with 3D Flex System Evo™ for enhanced mobility
• Durable water-repellent synthetic upper with abrasion-resistant rand
• Ergonomic 4mm footbed and polyurethane foam midsole for cushioning

In daily use

On trail, the boot's traditional lacing with hooks secures the foot firmly, while the all-round protective rand shields against rocks and scree. The semi-automatic crampon compatibility allows use on alpine approaches, and the partially recycled materials in the rand and laces reflect a sustainable design choice.
