Nice boot, looks good with jeans and other casual style pants. In Kalso Earth shoes I normally wear a 6 1/2 and they work great because of the wider toe box but I would say this boot fits a tad on the small/narrow side. These are a slimmer fit than the Kalso styles and I probably could have worn a 7 but it wasn't available.  I can comfortably wear the 6 1/2 with thin socks which is ok because I live in a warm climate. If you need thicker socks I definitely recommend going up at least a 1/2 size.  They are comfortable for all day wear and walking and the side zipper is a great addition so overall I am happy with the purchase.
