I own several pairs of Earth Shoes, all in my normal size (6) and they all fit great. I bought these, expecting them to fit (like the Razr sneakers did), but they were too small. Been waiting for a 6 1/2 to become available, but no luck. Anyway, I'd recommend ordering a 1/2 size up, like several others have. I wish I'd listened, but I used the very similar Razr sneakers as a guide instead.
