Thanks to a deployable waterproof extension, the Floodline Slough Boot goes from rubber boot workhorse to thigh-high waterproof protection in seconds. For hunts or workdays that turn semi-aquatic, the 4-layer construction keeps you completely dry when water crossings get a little tall. An air mesh grid liner boosts circulation and the EVA midsole furthers that comfort underfoot. Step with confidence in mud, muck, or even submerged thanks to the optimal tread pattern.
