I've had several of these.  I really like the fit, but if they get wet they smell like cat urine.  New Balance replace 2 pair a year or so ago and the new ones did the same thing.  I've recently (April 2015) purchased a pair and now they smell.  Bad problem - lots of people are complaining about it online.  Not just this New Balance shoe, either.  Hasn't been fixed in close to 10 years.
