I love my Chucks and have 14 pair which range in size from 7-8 in womens. Most are 7 1/2 so I felt comfortable ordering that size, however they are a smidge on the large size with some extra toe room. I did not have the same problem as other reviewers in confusing men's and women's sizes and I'm not certain why these are a little big, but I believe a size 7 would be too small and frequently wear my current pair despite the extra length. My advice would be to order the size you normally wear then go from there as far as your individual size and needs. Some people would be bothered by the roominess, but it is not enough of a problem for me not to wear the shoes or return them.
