Sock repair?

I just noticed that the bottoms and heels of my favorite socks (worsted weight wool) are wearing very thin. I thought maybe duplicate stitch in those areas would help, but I would like to hear y’all’s ideas.:??:??

here’s a bump for you. i’m wondering about this too.

Hereis a knitty 101 on repairs…you have to scroll down a bit to get to socks… I haven’t had a pair wear out on me yet…but I think that would be a great reason to buy some special new yarn and knit a pair just for you :happydance:

Here is another site for you

The duplicate stitch would work!

Thank you all for those sites. They both say to use Duplicate stitch!!! I’m off to fix my socks. thanks again.
