Guide approved and river tested, Simms® Guide BOA® Felt-Sole Wading Boots for Men stack agility and stability in your favor out in the water. These performance wading boots utilize waterproof nubuck leather, high abrasion textile panels, and welded thermoplastic polyurethane (TPU) film in high wear zones for a rugged and protective upper. Rubber overlays at the toe and heel add even more protection. Outfitted with the BOA Fit System, these boots offer unmatched lacing simplicity and security you can operate with just 1 hand. Full closed-cell neoprene foam linings offer welcome comfort inside the boot. Time-tested felt outsoles deliver a sticky grip over slippery terrains and surfaces, while TPU outsole plates improve stud and cleat retention. Pull-on loops at the back of the boot make it even easier to slip the boots on or off. Manufacturer style #: 13510.
