These Sanuk Paradise flip flops are wonderful--and they're made out of real yoga mats too! I would definitely recommend sizing one whole size up from what you normally wear because unlike other Sanuk sandals, these run small. I'm typically a size 8 and had to exchange them for a size 9. I like my flip flops to have an edge behind my heel in case my foot slips out, and the 9 give me about a half inch of space that I need. I can't wait to wear these this upcoming spring and summer. They appear to be well made too, so I'm hoping these will hold up for a long time!
