Get these , they're so awesome and totally worth the price. They're well built and will last you 2 or 3 summers. This is the second pair I've gotten. They're the only flip flops you're going to find that actually have a bit of arch support and are actually sturdy and solid without being too heavy. There's even bottle openers on the bottom which is pretty badass.

They don't come in half sizes. So if you normally wear a half size, round up instead of down as they run just a little bit small. I normally wear a 12 but a few brands of shoes fit me at 11 and a half. I got my flip flops at 12 and they're perfect.
