I would recommend buying some higher quality socks, I have started ordering Darn tough and they are holding up well, I hit 10K steps everyday and not a single one has had any indication of anything like this happening yet. meanwhile I would have gone through a few set of cheap socks.
I have almost exclusively darn tough socks now and have for over 15 years at this point. I do eventually get worn areas in them but I never let them get anywhere near this bad. A small section of padding worn out is enough for DT to replace them for me. My main hobby is backpacking though so they get used hard and often. I would guess they last somewhere around 500 miles per pair for the micro crews. The business socks are also nice but wear out faster.
+1 for Darn Tough. I go through a lot of socks but my two pairs of Darn Tough socks are still going strong, despite one of them having a hole melted through it by?? a spark from a campfire?? I thought it would be the end for that one but it's barely noticed.
