The Arc'teryx Men's Acrux TR GTX Boot is choice for multi-day trekking and backpacking through challenging terrain in varying conditions. Gore-Tex gives this boot phenomenal waterproofing with comfortable breathability built for wet weather in any season. Its stable, supportive construction pairs a SuperFabric upper with a TPU chassis around the arch and heel. Vibram's rubber sole comes in a special MegaGrip compound for better traction when the trail gets rough. Arc'teryx slipped an OrthoLite footbed above the shock-absorbing, cushioning EVA midsole to customize your footshape for comfort.
