I bought two 3-packs of these socks for work. I work 4 days a week. That means, at most, I wore a pair once a week. They felt great at first.

They began wearing thin on the bottom of the heel after approximately 6-8 months... On EVERY pair! The quality just isn't there. 5.11 makes some things well, these socks are not one of them. If they can't last a maximum of being worn 52 times, don't waste your money.

Poor quality. I would never recommend these socks to anyone.
