Socks are worn for 99% of my waking hours. They only come off in specific circumstances, normally involving water.

The socks must be well-fitting and put on straight, pulled up to their natural height and tightness. I prefer socks that come halfway up my shins, and I only wear ankle socks when working out.

The socks must be a matched pair. No mixing between different colours, cuts, brands, etc.

No holes allowed; if a sock gets a hole of any size, it immediately goes in the garbage. The widowed sock goes on my dresser until an appropriate mate is made by the splitting up of another pair.

On the other hand, I never sleep in socks under any circumstances. I find I get too warm.
