I was so excited to get my new KEEN's only to have them not fit. I normally wear a 9 but sometimes an 8.5 but I thought to error on the side of caution and ordered the 9. They were too small :( I still wanted them so I decided to return them and order a half size bigger (9 1/2). Now I'm really disappointed because when I try to reorder just a half size larger the price goes up over $40!!! I just don't understand why one half size larger will cost me an extra $40. Not sure if I will reorder now.
