Simply put - New Balance makes the best baseball spikes.  Period.  My son wore his last pair for two long baseball seasons.  Usually, this would destroy spikes.  He wore them through everything.  After games and practice he just threw them in his bag where they were crushed by the rest of his stuff.  I figured they would be shot, but they are still in great shape.  He got a new pair this year because of a color change in the team.  The old ones are now his back up pair, and they still look good.  The new pair are wearing just as well, and should easily last another few years with no problems.  There is a reason you are seeing them being worn by more and more players from the school yard to big league parks; these shoes are second to none.  As a side note, I bought a molded pair of baseball spikes for a softball league.  They are equally awesome.  More comfortable than my sneakers, and they look great too.
