I have been looking for a good pair of boots for being out in the yard in the winter, shoveling snow, etc for quite a few years. We live in Syracuse, NY so snow is something we are intimately acquainted with. This is the first pair of boots I have had since my old Matterhorns from my Active Duty days gave out - many years ago.I was looking for a pair of boots that would keep my feet dry, were at least somewhat warm, and weren't so short that snow would easily get down inside them. Although we have had mild winters by our standards; for the last four or five years before this year we have still been getting 65-75 inches of snow with a few big storms each year. This year we are already over 100 (start of the last week of Feb).We have three dogs and I am out in the backyard a lot with them in the winter. Additionally, I spend a good amt of time shoveling snow. I have had the boots for a month and a half so far and they have more than met my expectations. To be honest when I first took them out of the box I was struck by how tall they were. I must have missed that in the product description. They are just a shade under 18 inches, which has ended up being a very good thing, with all the snow we have gotten this year. There are plenty of spots in the back yard where the snow is a good foot to foot and half deep. So far I have not had any issues with moisture getting into the boots. The rubber seems pretty durable, hopefully that is the case and will remain so.Usually I have on a pair of wool blend socks (one pair) when I wear them out. Sometimes I only have a pair of thin cotton calf socks on. My feet have only gotten even slightly cold one time; and that was just starting to feel it a little. We had a brutal cold snap where the temp was getting below zero with the windchill and I was outside in them for about 30-45 minutes that particular time. Admittedly, I usually am not in them outside for more than 15 - 45 minutes at a time. But, other than that really cold period I haven't even felt the cold in them; and as noted above most of this winter I have been standing, walking, or shoveling snow that is multiple inches deep.The only negative to these boots isn't the fault of the boots, its my joints. I am in my early 50s and put a lot of hard years on my knees. They are both going to need to be replaced in the near future. So sometimes getting them off is a little hard. But, even that isn't as bad since I discovered I could use the little notch on the back to use the other boot/foot to push/pull it off.I am hoping to get many years out of these boots. However, they have been so great thus far that even if I get only two or three years out of them I will consider it money well-spent. I can't say they would be good if you had to wear them outside all day since I don't work outside; although I would think they would probably be fine. I would also note that they don't have much support; so that might not make them a good choice if they had to be worn all day and you need good support.If you are looking for boots that will keep your feet warm and dry for the occasional trip outside, shoveling, walking, etc these boots are for you. I came so close to buying so many other boots; so very glad I kept being so picky - I found these! Highly recommend them for periodic short uses like I noted!Lastly, I would say the sizing is pretty true size - editing this to specify that point a little. I wear a 9.5 in shoes/sneakers. The 10s for these fit well.Update - I wore these outside for just over 3 hours, shoveling snow and using a roof rake. It was only in the high teens, low 20s, with a pretty good wind. I had on a good pair of wool blend socks, jeans, and a pair of fleece pants over the jeans - and the legs of the fleece pants over the boots (right down to the top of the foot. My feet didn't get the slightest bit cold. In fact with the two pair of pants and one pair over the outside of the boots my calves got a little sweaty. I would give these a 6 out of 5!
