Bought these socks to replace the last batch I bought about a year ago. As soon as I put them on my feet I could tell that they were not the same. It turns out that they are now 54% wool as opposed to 64% from a year ago. The socks are clammy and feel like synthetic rather than a nice wool running sock. I will not be buying anymore Smartwool unless they return to the same level of quality and increase the wool content again. Very disappointing.
