Got a size up, great move. Usually pull on/off and don't tighten laces. Wear all day at work ... quite warm and comfy. I wanted sorrels, but the reviews were so bad I had to try something else. These are great, lots of compliments.
These are fantastic boots. They do run tight though. I got a 7.5 first but exchanged them for an 8 and now they are perfect to wear even with a pair of thick socks. They are extremely lined and feel very stiff at first but they are incredibly insulated and keep my feet ridiculously warm and dry. They are a bit heavy and not easy to jog or hike in, but they are absolutely fantastic for shoveling the driveway or walking the dog in the snow.
These are a very well made quality boot. Very warm and waterproof! I think they fit small though. I wear anywhere from a size 5-6 and I ordered a 5 1/2 which I had to send back. I ordered a 6 and they were still a little snug. These have a pretty thick liner and I had to really work at getting my foot past the ankle area since that part has extra cushion. My feet are a little wide and I do have a high instep. Once I get my feet in they are plenty long and comfortable, although I do wear thinner socks with them. I would suggest ordering a 1/2 or even 1 size larger than you normally wear!
Great quality and very warm. I have a VERY high arch and I have trouble with all shoes/boots, the fit is snug but I can deal with that because these are amazing in every other way. Very nice boots! I can't wait for winter!
