Does not comply with 670-1
First and formost, if you're in the military, these do not comply with 670-1. They are not rough out leather, and no commander in his right mind will let you wear this (learned this the hard way).
Second, they are vinyl, they will not break into your feet, they make your feet sweat like crazy, and the just plain don't feel good.
I've got a pair of blackhawks other boots. They are much better in every aspect, but they are breaking down a bit quick.
