This is a nice minimalist shoe that fits me like a slipper.  I bought an 11 and wear a 10.5w NB Tennis and 11 NB running is usually slightly roomy.  These were a bit snug but loosened up after the first outing in them.  Now I'm sold!  I tend to buy the NB branded minimus trainers but these are better.  Fit better.  Feel better.  Look good too.
