The La Sportiva Trango Alp GTX is a 3 season alpine climbing boot. A combination of Idro-Perwanger Roughout leather and synthetic leather create a durable upper while a sticky Vibram sole rounds out the boot. The boot accepts semi-automatic crampons and has a 3/4 shank & 3D ankle flex system to allow comfortable climbing.
