these shoes are not only adorable but super well made--They do run about one sz large--I ordered a 6 and wear a 5-5-1/2-,but with an insert and or sum footies/or socks  they are fine --plus you can tighten buckles--For 13.00 and sum change, I am more then pleased--and still would be if I had paid $35-45 for therm. I have several other styles of rocket dogs but these are by far my favorite and with the fine quality they will outlast the others..They are a flat shoe so you  may want a thin insert in them even if they do fit--They arrived 4 days early ...Great transaction all around
