Should you size up in TOMS?

Hey there, I've been eyeing a pair of TOMS shoes lately, and I'm wondering if I should size up. I've heard that some people find them a bit snug, especially in the toe area. But on the other hand, I don't want to end up with shoes that are too big and slip off. Have you had any experience with sizing in TOMS? Do you think it's better to go with my usual shoe size or to size up just a bit? I'd love to hear your thoughts on this!
