This boot gets 2 stars because they are freaking awesome, until you wear them for 40hrs+ a week for 2 months.  First thing that went on the first pair was the boot strap on the back after 2 months...Completely pulled off of the boot.  Second thing was the sole separated from the shell.  First thing to go on the second pair of boots was the bootstrap on the back.  After a few months it separated completely from the back.  Same story as the first pair I owned.  The o my thing that gets these boots a 2 star other than how awesome they are for the first two months is the fact that under armor will give you a new pair if you send them in and complain.  But why do we even have to do that?  Come on under armor...get your crap together...these boots changed the game.  Make them last.
