I wear size 10.5 street shoe. I switched to these shoes after deciding the moccasyms just couldn't accommodate my lurpy feet. Great decision. First off I also found that they size about a half size bigger than the mocs right out of the box. A 10 in the mocs had my toes in a foot fist about 75% compressed. I wanted a trad shoe that would allow my feet to lie flat. A 10 in these puppies had my toes slightly curled but just enough so that when they were fully broke in, they fit like a glove with my feet flat!
