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 http://www.hjsstudio.com/darn.html

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.
