>>2820817 (OP)You, OP.
(You) are disgusting. It's (You).
Not only you, but me too. Every human. Every human is a source of fucking FILTH and GRIME. Within our grease and dirt we fuel micro organisms and they produce even more nasty gunk.
When (You) are in the sock, it will become nasty.
There's nothing to prevent this. No product on earth can or will fix this problem.
Embrace filth or change clothes. It's that easy. If you really really really do not want to change fucking socks, you need to just wash them between use.
You have one alternative. It's not necessarily a solution and doesn't contradict the above statement about no product fixing this problem. This is a workaround. You can chop your feet off and get prosthetic feet, they don't produce filth and you can wear the same socks over titanium or plastic year round worry-free, and they probably won't even smell unless you submerge them in water or get rained on.
The trick here is that when your prosthetic is in the sock, it's not (You), so the sock doesn't become filthy.
Just change your fucking socks and keep your feet bro they're small and easy to carry extras. You can even wash them in a river on a sunny day and air dry, but you need multiple pairs to allow for this.
