I normally wear a 7 1/2 wide in a shoe, wide at the toes, narrow, and short at the heal. I ordered these Sloggers in the 8. With socks on these fit like a glove. They don't move up and down on my heel as I walk. They're not scrunching up my toes. They fit great! These have a very solid sole, another plus in my book. Working around a small farm, having a pair of waterproof shoes that fit so well is awesome! Other reviewers have mentioned the "short" heel on these shoes. They're correct, but that short heel fits my short, narrow heel just fine. I also do not think I would want to wear these without socks because they're made of a solid material. In other words, they don't breath, and would probably cause my feet to sweat. If I can remember to do it, I will update this review in the Spring after I've had a winter to test them out in. My hope is that these will last a long time. We'll see.
Update, it's July 2018. I've been wearing these shoes through Fall, Winter, Spring, and well into the summer. The only draw back is they are not suited for cold gound. In other words, they will not keep your feet warm during the winter, while working outside. They do keep your feet dry. I love these so much that I bought a second pair to keep for wearing on those rainy, running errands days. The second pair goes well with my blue jeans, and again, keep my feet dry, and here in NC it's been a rather wet summer. As for the first pair, nothing is wearing out on these shoes!
