These are tip-top socks!! I always wear 2 pair of socks; one thin, then a thicker, comfy pair over the first ones. These socks are warm, and fits a size 15 foot (which are hard to find those sizes). A little pricy, BUT, good name- good quality, good product!!!
True to size.

Warmest socks I have ever worn. Just bought 5 new pair after my previous ones finally wore out after 10 years of frequent use during the winters. Not itchy. Expensive but worth ever penny!

Miles To Go
I am a walker and have only put 67.5 miles on the new replacement soles of my boots and the heels are beginning to show wear, but the socks are still holding up. Talk to me when I log 500 miles and we will see then.

Awe some socks!
These are the best socks on the planet! I'm a huge hiker and I can still wear shorts with these socks because they go high enough up to my knee and keep my feet and legs super warm even in minus 25 degree weather! I wish they made men's leggings or long Johns out of this material. Incredible socks!
