My sock drawer is full of cycling socks. It's pretty much all I wear anymore. I've given up on style and have gone straight to function. Cycling socks fit better and breathe better. I wear them with suit pants, shorts, jeans and sometimes during "business time" (I think you all know what I'm talking about. If not, go watch the Flight of the Conchords clip.)
I used to wear the low cut cycling socks but lately I've really liked the higher cut. They look goofy with lycra but that's why I like them. And I really like black socks. Black socks with shorts is a fashion "No No" but I think it's a cool look. Just don't wear them with sandals.
These are my thoughts on cycling socks.
