Obviously this isn't directed towards any Obama voters, I'm looking for input on guys who actually work for a living, standing on concrete and such. I'm a machinist, on my feet most of the day, often getting oil and coolant on them. For the past 20 or so years I've worn rockies, my last two pairs have sucked, not as comfortable or as durable, my two main concerns. What does everyone like? I don't mind paying for quality, 150-200 is about normal for what I've bought in the past, a little more is fine too if its something decent.
