I have super tiny feet. I wear a 5 in heels, boots is about a 5 1/2, but like I said, on the small side. Even though the reviews said "runs small" I went with a 6. I mean, 6 1/2? For me? Crazy! I figured a 6 would be big and just wear with thick socks. I was super excited to get these, they looked so cute! Well, put them on and...should have listened! Super small! My toes were at the top, not just touching but smooshed! For some reason I decided to zip them up anyway...could barely zip. These are going to have to be exchanged.
