I typically wear a 9.5 B and have a high arch and instep. I ordered a half size up (10) which is perfect in length, no trouble getting them on, and  very roomy in width and across the top when wearing regular socks. I am able to lace them tight enough for a comfortable fit although still roomy-- with thicker boot socks they should be perfect and I'm guessing would still accomodate a  wider foot. Height is great for snow, and they are toasty--probably too warm to wear inside for long at normal room temperatures. I can wear bootcut jeans over them with no problem, and there is room to tuck in pants also thanks to the laces. They are comfortable. I wouldn't call them a fashion statement, but maybe they are more so in the smaller sizes. Overall I am happy with this purchase for cold/snowy weather use.
