Just got this shoe and have only used a few times, but so far, so good.  Snug fit and a bit of a different feel if you have not had a minimus shoe (I had not).  Definitely need to get used to it which isn't hard to do -- although I had expected this based on other reviews.  I am not a marathon runner by any stretch (more like 5K!) but this lightweight shoe is comfortable and performs well when I am running.
