I like this shoe, but the sizing is way too large. I normally wear a 10 in street shoes, and 9.5 in dress shoes. In fact my other pair of Clark's are 9.5, so I thought that would be a safe bet. Nope, I tried them on and there was, no kidding, almost a full centimeter of space between my heel and the back of the shoe. I don't know how many sizes that is. I returned these and will try a full size down but only if there is a free return offer on the purchase.
