The price on these socks is a great buy, and they feel good. But. . . don't expect to get a lot of wear out of them. I've bought two sets, and they wore out so fast I won't do it again, despite the great price.
They wear out in the heal (gets real thin real fast) and in the ball of the foot area (real thin real fast).
I was so surprised, because normally I have high regard for Costco products. So I thought that I should probably tell them about the problems, because it's hard for me to believe that they would keep selling them if they knew. But I haven't yet.
So, buyer beware for now. On the other hand, for this buyer, they would quickly feel like his usual "no socks" method, which might be fine.
Anyone else have experience with Costco wool socks they want to share (on 'Gear' so we don't hijack this thread)?
