I admit I have not taken these on a long run yet. I just retired a pair of Nike Frees because my ankles were starting to ache and the 150+ miles I had put on them was obviously enough. These arrived in the mail yesterday and I really like them. The shoe is very light - what I liked about the Frees. However, the toe area is definitely roomier. I also like that the bottom just seems more durable. It doesn't hurt flexibility or lightness, but definitely adds something in the way of support without adding inches in foam. I look forward to taking these on a long run and training in them. They definitely seem more durable than the Frees.

UPDATE! I just took them out on a 4.5 mile run and they were great. Light in the right ways yet more stable in the ways I needed. They are less flexible than the Frees so my ankles are adjusting, but overall I feel much less jarring wearing these and it was exactly what I was looking for.

Several weeks later update...well, I am concerned these could be causing me issues. I am starting to have heel issues on my right foot. I have never had this before and I think it might be PF. Now it could be my increase in mileage or it could be the shoes. I ran with the Nike Frees today and didn't have the pain while running I was beginning to have with these. I am hoping it is not the case because I really like them....
