Light, durable, and stable for the most demanding trails, the XA Pro 3D Ultra 2 GTX has a streamlined profile and great durability with a new outsole design, plus the year-round climate comfort of Gore-Tex. Great for a sprint-length or multi-day adventure race, these shoes have seam-sealed waterproof breathable Gore-Tex XCR membranes to keep your feet dry and fresh, while triple-density EVA midsoles absorb and disperse impact, which reduces jarring throughout your body.
