I just bought my second pair of these.  When I go the first pair, I wasn't high on the lacing system, but they are actually very quick to put on and off.  I've worn the first pair now for 3 rough winters in the NW, and they are warm and waterproof, and although they are a bit heavy compared to the more stylish "tennis shoe" style of "winter boots," they are real boots, and not a problem to walk in.  I frequently walk 2-3 miles a day in them.  The little drawstring gaiter at the top also is handy when in heavy snow, keeping the stuff out of the boots.

Update:  1/21/2015:  Bummer!  Got a second pair of these yesterday, and not only were they not at all as pictured (Boulder does NOT show here as being grey and black), but one of the lacing grommets was not riveted, just hanging loose on the string.  So my first pair is so good they moved me to get a spare pair, and now I'm off these boots.  Poor quality control and not at all as pictured.  The ones i got had a pale grey lower part and black uppers, which is not at all what "Boulder" shows up as in Amazon's product pages.
