I've been buying cheap, Target or whatever (Hanes) black socks for ages.
Somehow, they are all failing at the same time, with big ugly holes where my big toes go.
It isn't like I have big gnarly toenails or anything... I don't know why my socks keep exploding.
So, instead of continuing to buy cheap horrible socks, I have switched entirely to SmartWool socks.
Granted, they are 10x more expensive than shitty normal socks, but WOW they make a big difference.
As long as they hold up for at least 6 months at a time, I'll probably continue to buy them.
What socks do you wear?
