They do run small, though -- buy one size up.
Is Roxy true to size?
They have a nice arch support and are true to size for me. I wear an 8.5 and that's what I ordered. They are soft and have some give after breaking them in so don't be concerned if they seem snug at first because they will loosen up.
Do Roxy board shorts run small?
These Board shorts are nice because they have a longer inseam. Because they are technically "juniors", they run small, so size up.
