I’ve had to do 2 days in a row multiple times in my life, and they get gross really fast. I can’t imagine going for 3.

Had to every day with cotton. I can rotate my merino wool socks throughout the work week. 2 pair for 5 days.

Socks are for the weak. I wear sandals unless it’s a formal occasion and even then I only wear socks to protect my Jordan 1 low Pandas from me.

I used to wash them daily but it made them shrink a bit whereas wearing for 2-3 days makes the fabric a bit wider. As I have pretty wide feet, narrow socks just hurt at the end of the day. So I wear them 2-3 days depending on sweat and dirt.

I stumbled upon this thread and got really confused. Do people usually have sweaty feet? I tend not to wear socks except when I wear shoes. Otherwise, I wear slippers or go barefoot. Even when I wear shoes, I don't notice any sweating in my feet. I usually wear cotton socks though.

To answer the OP, though, my rule is to not reuse socks with a couple of exceptions:

• if I only had the socks (with the shoes on) for less than a couple of hours, I think it's safe to reuse the socks.

• if for some reason, I go to a place where I need to take my shoes and socks off (like if I go visit a friend) I would reuse the socks, of course.

Most of the time though, I just don't bother with shoes and socks if I can get away with it. It's too hot where I live to deal with socks.

Bought a marino wool shirt because i was told this. Still incredibly itchy even if it was better than regular wool.

If you are somewhere pretty cold and unsociable then fine. You could also wear two pairs at once, the woolen ones on the outside and washed less often than thinner ones inside to wash often. Done that. Works well. Again; cold, kinda not social.

4-5 in Winter and 1-2 days in summer

I put on new socks everyday. But if I get up early, and have to do stuff as soon as I'm up, I might put back the clothes I had the previous day and, like, prepare my son's breakfast, then I go take a shower, then I put on new clothes.
