Grabbed these for about $18 and they are very cute. The straps aren't super tight on my feet but I prefer shoes with a buckle so I can have it tighter around my heel. My feet don't slip out though. I wear a 9 but ordered a 10 and these fit perfectly. Definitely size up. My toes don't hang out nor does my heel hang over. I'd order the brown pair if they ever go on sale.

Edit: Walked around in them and they are comfy BUT the sound it makes when you walk is very annoying. I bought sandals similar to this on Amazon for $9 and they don't make that squeaky, flip flop sound as I walk. I guess I'll get used to it but for $18 I expected something more quiet.
