I have worn Clark's shoes for years, always a size 8, no guessing, always a good fit. These were my first flip flops however & when I put them on they were a bit short but more noticeably, too narrow. The sides of the widest part of my feet went beyond the shoe. They were pretty & made well but if you can I would try these on in a store first. Amazon's price was great & I was sorry to have to return them.
