First of all, this shoe is adorable. I purchased the green which is like a rich, jewel-tone green with a hint of teal in it. I've read that Ollio shoes run small but, since they don't offer a size 10.5, I took a chance and ordered my size 10. The width fits just fine but the length is just a little snug. I can feel my big toenail rubbing the inside top of the shoe but since the shoe is very flexible, I decided to keep them. I'm wearing them at work right now and I haven't had any issues with them so far. Super comfortable and cute!
