I love the improvement on these over the previous men's Nike Free Trainers but there's something off about this one. Improvements include comfort for wider feet, flexibility, great design, and stance. The two things that prevented me from keeping it was the heel to toe drop and a weird amount of support directly below the heel. I think if this is a Nike Free design, it should feel like I have simply an extra layer below my feet when standing flat. It doesn't because of a slight drop and what feels like Nike Air right below the heel. Some others may like this design but it didn't work for me. I do think it's a big improvement though so hopefully the next design is even better.
