In July 2010 I was 4 months into a tour in Afghanistan. Our base was covered with 3-4" minus crushed stone. Walking on it all day was hard on the feet, more so when you were preparing to go outside the wire wearing body armor, helmet, two weapons and ammo and assault bag. Then one day we got a bunch of "care packages" from back home in VT and each one had a pair of darn tough socks in them, OD green in color. I put them on and was amazed how good my feet felt. Still have that pair plus several more, best socks I've ever owned!
