There are not really chunky.
They are a bit thicker than the thinner dress socks, ribbed, used to be called walking socks, and they are OTC that have scrunched down.
I have a bit of a fetish for wearing clean white OTC socks.
When I was a kid I read that Jerry Lewis when he became rich used to wear a brand new pair of white socks (and sometimes other colours) every day then throw them away.
It kinda stuck in my head as something to aim for.
