Columbia Men's Bugaboot Celsius Plus Snow Boot - Waterproof Winter Boots for Hiking, Snowshoeing & Cold Weather - Insulated & Thermal for Extreme Conditions

I just bought these, and I wanted to give my initial impressions. I have other Columbia winter boots. All the other ones I had to order up a full size to get a good fit. I did that with these as well based on previous experience with Columbia footwear. This boot appeared to be a half size too large. However, I would rather have too large than too small in winter boots. I am also somewhat stuck as Columbia does not do half sizes over a men's size 12. I ordered a size 13, and I imagine a size 12.5 would fit me perfect.The build quality seems very good with these boots. The insulation looks very substantial. I wore them around briefly. The boots were very comfortable, and there won't be a long break in period.I tested my boots by soaking them in a tub of water for several minutes. The insides were completely dry. I can verify they are waterproof.I will have to test these out this winter to see how warm they are. Despite that, I am very optimistic these will be warm. I will update this review at a later time as I get to wear them in a Wisconsin winter.Edit:I forgot to add in my initial review that these boots have a fairly substantial amount of room over the top of the foot. That provides enough extra room to layer socks. I also added a cheap ($12) Toasty Feet aerogel insole, and I still have room to layer socks. That insole is about 1/8" thick. Yes, there is a lot of room above the foot.
