Try wading all day in sandals or sneakers and you'll understand why we designed the Simms Intruder® Boot for saltwater wading. Whether you're in surf or exploring saltwater flats, these wet wading boots support your feet and let you move without worrying about what's under foot. You can wear them barefoot in warm water or with our Neoprene Wading or Guard socks when you need more warmth. A built-in neoprene sock hugs your foot for a snug fit, and a Vibram® outsole grips everything from wet rock to slippery wood. There's a fold-down gravel guard to keep out sand and debris.
