La Sportiva’s traditional mountaineering roots have blended with the innovation of the Aequilibrium Series to develop the Aequilibrium Trek GTX® boot, which is perfect for long treks and backpacking expeditions. A true balance between technical performance and comfort: the sole and midsole construction create a smooth rolling stride and essential support, while the Double Heel™ sole lug pattern creates maximum uphill traction and downhill braking for superb grip and performance on technical terrain.
