timberland pro series....only boots i will ever buy. i keep trying new boots and always go back to them. ive ran through redwings, cat, dickies, wolverine, rocky, and a few other misc boots...nothing compares IMO....their new hyperion boot also has vibram soles, cant wait to test them out (they arrive tomorrow)....my last pair lasted me for 2 years of solid abuse (UPS is like the grim reaper of boots/shoes).....normally i blow the toes and soles out of boots in 6 months, so for these to last me almost 2 years, i couldnt be happier
