I no longer live in a wool-sock climate and these are taking up space. Should fit women’s 7-9.5M or men’s 6-8.5M. I think the two pairs on the right are wool blend socks from target and have been washed but never worn. The black smartwool pair is a thinner wool and never worn. It has a cable knit detail. The shorter purple smartwool pair was maybe worn 1-2 times and also a thinner wool. The purple and brown/gray (classic hike style?) smartwool pairs have a bit more wear at the back of the heel (pictured) but still have lots of life left.
