Have had these for about a week now--they did indeed run SMALL, so get a 1/2 size larger than you usually get.  I usually get 9 1/2, these 10s fit perfectly.  They were comfortable out of the box, not much break-in needed.  I'm used to Nike air, so the gel was a little different, but really nice.  If you're looking for standard blue-white cross trainers, I don't think you can beat these, including the price.

Can't speak for their durability, but so far, they have been great.
