I've been wearing Reefs for years, and glad I paid attention to the recent reviews. I'm a size 8, and bumped up to a 9. I could probably do a 9.5, that's how off the sizing is now. Other than that, the band is snug, but that will fix itself once I break them in. They're still the most comfy flip flops you can get and are worth the price, just pay attention to the sizing.
