It took about a month for these to feel really comfortable (No blisters, just conforming to my feet). I walked through water puddles that came higher than the rubber soles. The water just repelled off the boots.  Only problem I've found so far is that the waterproof liner makes my feet sweat.  Probably will be great in the winter.  Of course now the Army changed boot colors just after I bought these, but fortunately I have a few years to change over.
