No, but they shed water well. I treated mine with Sno-seal soon after I got them, and have worn them in rainy and snowy conditions many times without any wetness leaking through. Nevertheless I'm sure that my feet would be wet if I walked through 3 inches of water for a quarter mile. BTW, the rubber compound in the soles provides fairly decent grip on ice and hard-packed snow.
These have some water resistance, but they are not waterproof.
