Sapatos de montanha La Sportiva Aequilibrium Speed GTX - preto/amarelo - tamanho 47

Alpine climbers moving fast over mixed terrain need a boot that balances precision, protection, and low weight. The La Sportiva Aequilibrium Speed GTX delivers exactly that, combining a semi-cramponable sole with a waterproof GORE-TEX membrane and an integrated gaiter for seamless performance on technical routes, glaciers, and via ferrata. The double construction pairs a traditional inner boot with a stretch outer gaiter, keeping debris out while allowing a full range of motion. A Vibram® SpringLug Tech outsole with Impact Brake System provides reliable grip on rock, snow, and ice, while the nylon and carbon midsole with PU foam offers the stiffness needed for front-pointing without sacrificing walking comfort. The water-repellent high-tenacity fabric upper is reinforced with Honey-Comb Guard™ and a TPU anti-abrasion film, ensuring durability in demanding alpine environments. This size 47 model comes in a black and yellow colourway, ready for fast and light ascents.
