I loved these shoes man!  I wore them full-time for like 6 months running and working outside.  I was pretty hard on them during that time (digging hundres of fence post holes and mixing cement, demoing/building back decks, etc) and they soles are now starting to seperate from the shoe.  If all you're doing is wearing them like normal people do, then they'd likely hold up much longer.  Even though they didn't last as long for me, I'm still not mad at you Puma!
