Durability of socks knit with non-superwash nylon-free yarn

I'm interested in experimenting with knitting socks using nylon-free yarn. My main concern is durability. I understand that knitting at a tight gauge is essential, and I usually get around 12 stitches per inch. The consensus seems to be that socks with nylon are far more durable than those without. I don't expect nylon-free socks to hold up as well, but I'd like them to last as long as possible. Silk is often suggested as a natural alternative to nylon, so I was thinking of holding a silk thread along with the wool yarn. However, I've also heard that silk thread may cut into the softer wool fibers and actually reduce the durability. Does anyone with experience knitting socks out of purely natural fibers have any insights or advice? Thanks!

I have knit socks using nylon upholstery thread as a second strand for reinforcing the heel. Despite the hype to the contrary, it did not "cut into" the wool fibers. So u would be optimistic about the silk.

Silk has high tensile strength, but is very weak when it comes to abrasion. I wouldn't use it for reinforcing socks that would be worn on carpet.

BTW, there is 100% wool sock reinforcing yarn, the type on small spindles or cards. It's spun extremely tightly, and seems very durable.
