I got my first 7 pairs of Darn Tough wool socks in 2015. I washed them (inside out) once a week. Then I got another 7 pairs about a year later. Now each pair is worn once every two weeks.

They show no signs of wearing out. I will likely have these socks for another 8 years.

I think OP (/u/Johnpecan) would probably like to know that his plan is solid.
