This boot is very comfortable and looks good too. I am a size 13 with a narrowish foot and have always found Merrell fit extremely well and their sizing is very consistent. If you have ever bought any Merrell and it fit well, you are that size in every Merrell. The boot is extremely waterproof, I live on the East coast where it rains all winter, which is why I bought this for shoveling the driveway and various things you need to get outside for quickly. The insulation is nice and warm and the boot height is perfect. The boot was a little hard to slip on the first half dozen or so times, but now it slips on just right. Glad I bought this!
