Hmm.. I'm having the same issue. I bought a size 7 and although they "fit", I feel like my toes against the tops / edge of the shoe sometimes.. I wonder if it's the back elastic that's pushing my foot forward. I'm ordering a size 7.5 and I'm seeing if they will fit better. I figured I'd rather have the extra wiggle room than having them hurt. And if they are too big, I could always put like a foot pad inside.
