Fit is comfy, haven't worn them in cold weather as yet. Hope they're warm!I was looking for a decent pair of tall boots to be warm in the winter. I wasn't too optimistic about being able to fit into them, but I wanted to know for sure since they *looked* like they might be big enough from the photo and description. So, now I know. The zipper is a bit hard to get up, but I was able to just about close them. 16 inches means 16 inches. However, they are a bit too tight to be comfortable on my calves for any length of time, so I will have to return them.That being said, the actual shoe part felt pretty comfortable! Especially for a rain boot. So I intend to get a different shoe from this brand at some point.These were absolutely worth the price! They fit and feel great. Easy to walk in and your feet don’t get tired. I went shopping with my sister in law (and believe me she can shop) after wearing them all day my feet felt great and this was the first time wearing them so that should be enough saidThis boot is definitely Sperry quality and comfort. I prefer a more rugged looking boot such as this one, and I love that it has some leather features to it that add just a bit of style. I can’t say enough how comfortable they are and how they hug my feet snuggly. I am very pleased with this purchase!These boots has to be one of the best purchases I have made on Amazon. They are so comfortable and warm and keep me dry in the snow and rain. I am more than satisfied with this purchase .These boots are warm, comfy and good looking! They will definitely work for wet wintery days as well as spring wet days.They are for work. Super cute and I love them.These boots are waterproof and they keep my legs warm. I’ve already had many compliments from strangers that say wow I like your boots. They fit just as expected. I would order these againGreat! Perfect accurate description.Great for cold winters with slush and snow!
