best socks I have ever owned. In fact, the first pair I ever bought is still very usable, no holes, warm, tough, comfortable. Worth every dollar you pay for these socks.
I've used my first pair on two long Sierra hikes in 2013 and 2014, as well as ski socks on at least 50 days on the slopes, and then as winter cycling socks for the last three winters, easily 5 days a week for about 4-5 months of the year, casual sock use as well.
Didn't know about the warranty, but as it stands, I won't be able to get a free pair to replace my original socks for quite some time to come.
