I ordered a size 8 when I'm usually 7 (sometimes 6.5 in heels). The outsole length of size 8 is 9.75". My heels slip in the back a bit but with an insert they should be fine. The ball of my foot is also a little wide; I don't need a wide-width shoe but I can't fit a narrower fit. The shoes fit comfortably at the ball of my foot, so I won't be exchanging for a smaller size.
