These are super comfortable, right out of the box. I was a little leary, due to the lack of reviews, but took a chance based on the low price.<br /><br />Word of caution. I have wide feet. I normally wear a 9 1/2 4E, sometimes even a 10 4E. I ordered these in a size 9 M, based on a review that said that a size 9 fit large and a little wide. These are absolutely perfect for my feet. If anything they tend a little big, and fit about the same as my  ASICS 10 4E. Long story short, I'd order these a size smaller than you usually wear if I were you. If you have very narrow feet you might do better to look elsewhere.<br /><br />Having said that, these are still ridiculously comfy. I would absolutely order again.<br /><br />Two possible detractors:<br /><br />The outsole is a little slick. Not a problem outside, on trails or sidewalks. They tend to slide a little on smooth floors, like tile or hardwood. This seems to be getting better the more I wear them. Maybe I'm roughing up the soles a little.<br /><br />Not very arch supportive. I've seen way worse, and they do seem to be fitting themselves to my feet the more I wear them, so maybe they'll get more supportive the longer I own them,<br /><br />Did I mention that they are ridiculously comfortable? I would have given them five stars, but honestly the advertised fit is a little off.
