Botas de montanha La Sportiva Aequilibrium Speed GTX amarelo preto tamanho 43 EU

Mountaineering boots built for fast and light technical ascents, the Aequilibrium Speed GTX deliver uncompromising waterproof protection and semi-automatic crampon compatibility in a streamlined, high-cut design. The Gore-Tex Performance Comfort lining keeps feet dry through glacier slush and spring snow, while the Vibram SpringLug Tech outsole with Impact Brake System provides confident grip on rock, ice, and mixed terrain. A medium-stiff flex and integrated quick-lacing system balance precision and comfort for long approaches and steep climbs.

Advantages

The Aequilibrium Speed GTX are engineered to reduce fatigue without sacrificing performance. The Double Heel™ technology and 3D Flex System Evo™ work together to smooth heel-to-toe transitions on technical ground, while the no-sew PU and EVA foam midsole with TPU insert offers reliable support for semi-automatic crampons. A full protective rubber rand shields the upper from abrasion, and the water-repellent high-tenacity nylon with TPU reinforcements shrugs off scree and sharp edges. At approximately 1.1 kg per pair (size 43 EU), these boots keep weight low for speed missions.
