Designed to not only keep comfortable in the river, but also maintain comfort on the hike to and from, the Simms Flyweight Wading Boot is the boot we need for venturing far and wide to find the perfect spot. From the lightweight, synthetic upper to the Vibram Idrogrip outsole, this boot is fully featured for wading and hiking. The outsole is stud-compatible in case we want to customize traction options, but grips rocks and trails on its own as well. Underfoot, a dual-density EVA midsole provides cushion to reduce fatigue stride after stride.
