I am now on my 3rd pair of these boots. I do a fair amount of hiking, about 15 miles a week, year round, in all weather. By far, these boots have been the most comfortable I have been able to find -- just take them out of the box, put them on, and go.
They are somewhat water resistant, but, unfortunately, NOT water proof. This has been true of all three pairs I have owned. Because they are so comfortable, I choose to wear them most often, but when I am going to be hiking through slush, mud, or significant rain, I choose my other, much less comfortable, but water proof boots.
I wish someone would make a truly waterproof, comfortable boot.
