It's not often that feet get all the glory, which is why we loaded these moisture-wicking ski/ride socks with details that make em' fit an feel the best. The new Function X combines strategic cushioning and thinner, more breathable panels on top of the foot to reduce uncomfortable brunching and pressure. The payoff? Superior grip, better tech, and more control as you hunt for the next powder stash.

My New Daily Ski Sock

"As a ski instructor, I spend a lot of time in ski socks. I have sensitive feet, so want a little extra cushion in my socks. But I also overheat easily. Those are frequently at odds with one another. These socks do a great job of temperature regulation while giving me the padding my feet desire. I've worn them on rainy days, subfreezing days, and warm, sunny days and had no problems with overheating or cold toes. The compression and cushion points around the socks are prefect for me. And the material is such that is I need to wear back-to-back days, they don't feel even slightly gross. These are the perfect ski socks for me. My other Darn Tough ski sicks are heavier weight and I don't enjoy wearing them on warm days, but these are great whatever the weather."

So pretty AND warm/functional

"I like all Darn Tough socks I’ve bought and these are no exception; warm, beautiful, peace of mind knowing they’ll last but have amazing back up! These have the added perk of thoughtful support because of the creative weave (at least that’s how I understand it). I’m loving them!"

— Cathy B. (5/5)

The best

"Oh my gosh. I have replaced all of our socks with darn tough socks literally. I love them. Have never been sooo into socks and my feet have never felt sooo good. They really are the best. I have always tried to get good socks. I think socks are as important as shoes for feet comfort and these are absolutely the best. I am forever hooked. Just get them and you will be glad. I got these higher ones to wear with my boots. I now have every height. All the best"

Perfect snowboard sock

"These socks took away the typical shin pain after a day of snowboarding, kept my feet warm and dry, and look really cute. Love love!"

Need to was n dry then reviews again. . .

"The design is beautiful. My initial thought is what happened to the perfect fit and wonderful cushioning? So, I want to wash AND dry them then give a second review. I'm hoping after a dryer they will shrink to my foot size. I don't mind that the sock goes on top of my knee as I have shot legs and expect 1 wash/dry they will be shorter. But the cushioning is not near the comfort from the crew socks I purchased previously. . ."

Most comfortable socks I have

"Most comfortable socks I have ever owned. The cost is very much worth it. I used to be a person who only bought cheap socks. I will only spend my money on this brand now."

"I have only worn Sarn Tough Vermont socks for many, many years. They are very well made. The company is so loyal to customers with a lifetime warranty with no questions asked. I actually returned my aged socks and received a comparable coupon to purchase any socks on their website. Highly recommend the socks and company."
