I bought them a few years ago at Dick's and have not seen them since. I love love love them even if they are heavy.
After a few years of hiking I'm still trying to find decent wool socks. I guess I'm one the few for whom SmartWool doesn't work well. They feel great and keep me warm, but don't last well at all for me, I'm hard on the balls of my feet, which leaves me with a large pile of future wristies.
Any recommendations for merino wool socks? The Tilley's Endurables don't seem like much of a deal if they want $7.50 per "guarantee" replacement.
