I'm pretty sure they're a 37, though I'm away from home at the moment and can't check. They might be slightly larger, but no smaller. The style is the "Emerald" by Everybody.
These are my absolute favorite summer sandals -- in the pewter color. I loved them so much I also bought them in a lime-y green and a natural beige color (tempted by a great sale), and those colors just don't work on me. I have duplicated the pewter ones instead and am seeking a new home for these warm colors.
You can see them here: http://www.amazon.com/Everybod.....B002K2S8U0 and on me here: http://youlookfab.com/welookfa.....o-skinnies The green color is more limey-green than what Amazon shows, and the beige has nice mottling with a slightly darker shade, like the Natural Glove color on Amazon but lighter IRL. Neither has been worn more than once or twice, and may not have ever been worn outside the house.
The leather is buttery soft and there is a tiny, hidden wedge heel (maybe 1.25"). I have very fussy feet and these don't bother them at all -- hence the feverish over-duplication.
Would love it if a frequent YLF participant could use these. Shoes on me, shipping on you.
