rounding up is too big
I typically wear a 6 1/2 and the product said to round up to the next size if you are a half size. I got a 7 and it is too big. My heal slips out a lot, esp. when driving. My friend who wears a 7 1/2 tried on my 7's and they fit her perfect. My advice would be to round down. Other than that, these shoes are so comfortable! It's like I'm not wearing shoes, yet I can stand on my feet all day long, chasing twin 5 year olds and a 2 year old. I even do walks in these. Love them!
