One caveat: if you have one foot smaller than the other, like I do, these may not work for you. I have one foot that is 1/4 size smaller than the other. Because the rise is so high on these, my feet slide to the toe box. I could go with the smaller size and suffer through stretching out the shoe on the larger foot, but it's not something I can do, because the larger foot was too difficult to get into the shoe. Order your usual shoe size and they will feel a bit tight. But it is necessary to stretch them and expect tightness at first. If you go a 1/2 size bigger (I ordered both 7.5 and 8) then when you wear them longer than 15 minutes, your foot slides towards the toe box and you end up with your heel coming completely out of the shoe as you walk.

I really wanted these to work, but my odd-ball feet wouldn't let me.
