The Vibram Idrogrip outsole secures your footing on rocks and slippery bottoms, as you move from trail to bank to launch. The G.O.A.T. construction distributes pressure during long walks to the station. Woven TPU upper reduces water absorption after repeated entry and exit. The draining EVA sole evacuates water with every step to keep weight constant. Brass eyelets and hooks resist prolonged contact with water. The sole accepts studs and Simms studs to adapt grip to the terrain.
