These are nice slip on waterproof shoes! They were loose on my husband he wears a 10.5.Product is not the same quality as I usually expect to get from Clarks. I have several other pairs of Clarks and these are quite a bit larger than usual.I originally ordered my typically shoe size of 10.5, but they were huge. I reordered a size 9.5 and they fit perfect. They are comfortable and look great as a casual or business shoe choice. I’d absolutely follow the advice of some of the other reviews and order a half size or full size smaller than your normal size.A perfect shoe for light walking in a casual environment (museums, the office, etc). High quality material and workmanship in a sleek looking shoe.Color was a little darker than expected. But I guess some color variation is normal with leather. The fit though was a little bit of a disappointment from Clarks. I have two other pairs of Clarks in size 9 regular that fit perfectly. These however felt about a half size too big. Very roomy in the toes and the collar felt a bit loose with some chafing on the back of my heel when walking. The right shoe was also noticeably larger too. Overall, felt a bit clunky and not as good looking in person as in the pictures. I love my Clarks shoes, but these were a bit of a miss.Size is not accurate I went down a 1/2 size and still too large / long. Tried twice and gave up.As of today, the Clarks shoes have replaced my 18+ years wearing Merrell slip ons. Yes, they are that good.Nice shoe but a bit too large. I will wear with cold weather socksThe height of the boot to accommodate the arch of the foot is too low. This makes the boot uncomfortable to wear. I recommend a slightly higher vault of the boot in such a way that the boot doesn't slip off. This could have been a good purchase, otherwise.Great shoe for winter wear, easy on and off. Very comfortable as well.Disappointed with the fit
