I love these shoes.  I've been using the Nimbus for the last 3 versions and had 4 pairs of them overall, 2 12s, 1 13 and these 14s.  Everything I go to get new shoes I try on others just in case, but these always bring me back.  They hug your feet like you are using a tempurpedic pillow.  Fantastically comfortable and I can run all day in them.

I run 10-15 miles at a time relatively consistently and think they respond pretty well.  Maybe I don't know the difference, but I know my feet never hurt when I wear the Nimbus and I can't say that for any other pair of running shoes I've tried.  They just really take care of your feet.

I have a rather wide toe area and I've seen a lot of people say the toe box is small.  I guess they have much wider feet than I do because these seem to fit about the same as the 13, which was smaller than the 12, but it's not that much smaller.
