Darn Tough= darn good

I purchased a pair of these socks for $16 in Manchester Center, Vermont in 2007 and used them for the last several hundred miles of that hike to Katahdin. Then they lasted the whole
2,670 miles of my 2012 PCT hike, where they developed a couple small holes around the heels.
Darn Tough boasts a lifetime guarantee, so I went to their web site, and sent them to the owner’s address ( I did wash them twice).
Two weeks later, I received a UPS box with this EXACT duplicate ( color, model, and size) pair of socks.
I’m saving them for my upcoming attempt at thru hiking the 3,000 mile Continental Divide Trail.
I’ve tried numerous brands of these merino wool type socks and Darn Tough have made it to the top of the list.
