Draining System A lightweight, mesh upper and drain ports in the outsole work together like a sieve. You’ ll push out water with every step, preventing excess water weight. Anti-Mud Traction Anti-clogging rubber and the unique spacing of the outsole lugs provide traction that lets you dig in as the mud falls away.
