I am a sweater.  When I got out of the shower and put on these liners, It really did feel like vicks vapor rub on my feet.  They immediatly wicked away the moisture on my feet, making them feel very cool and comfortable.  On a rain-soaked, 40 degree, March hike in Michigan, coupled with a nice pair of Darn Tough Vermont merino wool socks and gore-tex boots, my feet stayed dry (sweat included), comfortable, and cushioned.  I have never had a better experiance on my feet.  When I got home after seven hours hiking in the rain, I took off my socks and gave them a whiff.  They smelled brand new.  I was shocked and amazed.  Great socks!  Treat yourself to a couple pair.
