I'm in love. Pulled them out of the box and ran six hilly trail miles. My feet aren't tired or sore at all. They somehow give my duck foot shaped toe area enough wiggle room while still looking lean and mean. I love the combo of flexible sole for easier running while still feeling very stable side to side. The included insole is really solid and supportive and feels good on my foot but didn't dare use it for this long of a run so stayed with my Superfeet insole and the shoe and it got along fine. I have tried a lot of shoes trying to find just the right fit and this is IT. Really nicely made quality shoe. Next jaunt for me and my Lightnings - a 15K. Oboz is my new fave shoe company.
