After reading other reviews, I ordered have a size larger than my usual size 6.5. My problem is not so much in the length/toe box area, as in the heel. My toes are shorter and the toe box is wide enough to accomodate my duck feet even with cork insole left in. (Without it, shoes are uncomfortable).
I wore around the house with no issues and decided to go for a short walk. 20 minutes in, I was in pain and a week later still have irritation on my heels. Since I have already worn them, returning is not an option and I cannot afford another pair. I will try to wear with bandages on my heels and hopefully that will work.
Also, the tread seems to collect any small stray stone or pebble in them, which is annoying because as the stones accumulate, you have to stop and pick them out because you can feel it.
