I have had these about a week, and have now worn them extensively, both for working out and for walking all over the city of San Francisco.  I agree with the other reviewers that they are super comfy and bouncy when you first put them on, but I had issues with the toebox after wearing them longer.  For some reason, after wearing them for a few hours, my toes would go numb.  I kept adjusting the laces so that the fronts of the shoes would be looser, to the point that the laces are actually lax at the front.  Only then were they comfortable for extended periods of time.  I usually wear an 8 or an 8.5; based on others' reviews that these shoes run a bit big, I bought the 8.  I do think they're the right size length-wise, but my feet might just be a bit wide for them to be perfect.  So if you have wide feet, you may NOT want to size down and/or these might not be the shoes for you.
