This is the third pair of New Balance 608s that I've bought in the last few years or more. The shoes are very light and comfortable.  However, there is one glaring problem with my last two pair:  The soles came loose starting at the heel... prematurely.  I havent contacted New Balance about this problem but I guarantee that I will if this third pair falls apart.  These shoes are too expensive to have the soles come off otherwise perfectly good shoes.  So while I gave them 4 stars, that rating may change down the road.
