Darn Tough - Best Socks on the Planet?

I received a pair of Darn Tough socks to test back in January 2014. The model I tested was Coolmax Boot Sock Full Cushion #1441. 

Here was my original finding:
Great fit: Darn Tough has eliminated the stitching by the big toe and little toe that can make the sock bunch up.
Comfortable: From the minute I put the socks on they fit well and were comfortable. No slipping.
Padding: Both under the ball of the foot and in the heal.
Wicking materiel: Your feet stay dry,which prevents hot spots and blisters.
Made in America: Enough said.
Lifetime Guarantee: You read that right!

As most of you know the hikes I do are very demanding. I have done about 10 hikes in these socks and I will be a lifetime customer.

Update:

It has been 3.5 years since I started wearing Darn Tough Socks. Since then they are the only hiking sock I wear.

I was given four pair of Darn Tough socks back in Jan. 2014. I have done almost 400 hikes and all four pair of Darn Tough socks are still in great shape!
I will be a lifetime customer.
