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.

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 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.

I usually swap clothes every time I take a shower, or when they get dirty. Nothing special happening that's very second day, but can end up being daily.

At the most about 16-18 hours.

Please consider finding a alternative to using wool. The wool industry is so cruel.

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.
