Step 1) Buy 10-12 pairs of identical socks.
Step 2) Wear socks, when any of them wear out, throw them away. Even a single sock, no need to throw away in pairs
Step 3) When you're low in socks (my limit is 3 full pairs), throw them all away and GOTO 1
I do have a few specialised socks for hiking and winter, but they're the unicorns in the bunch, I just need 1-2 pairs of them.
