I've been looking for a good replacement for my 13 year old Columbia boots that finally took a powder this winter.  I read the reviews to go a size larger, so instead of ordering my normal 8, I bought the 9, and find that I actually have a little wiggle room for my digits, but am really pleased with the fit.  Because I live in snowy Michigan, I wanted a boot that the rubber came over the toe of the boot and a bit up the side, and these are great for shoveling snow.  The calf portion is adjustable with the ties going up the side, which makes it easy to snug the boot around the calf.  I was concerned about B width because I have wide feet, but they snug around my feet perfectly and are really warm.  I'm a winter-walker and went for a long walk with them, no problem with comfort or over-heating.  They're very nice looking...I bought the grey because they were cheaper than the black and am very pleased with the color.  I'd recommend these boots to any snow-shoveling/winter walker!!
