Finer Fabric, Better FIT.
Whole Foot Comfort begins with premium fabric. That’s why we ground our knits with a higher quality 18.5-23.5 micron ‘fine-gauge’ merino wool. The kind typically used in luxury formal wear. This gives FITS a distinctly different, and superbly soft, feel unlike any other performance sock. Because no other sock is made like FITS.
All Day Comfort Guaranteed
If you’re not satisfied with your FITS® socks FOR ANY REASON, we’re going to work to make it right. There’s a form to fill out and a few hoops to jump through, but we keep it simple.

United StatesTHE BEST SOCK COMPANY
I love my skull socks, I have alot of fits socks, so comfortable
United StatesFit well, dry thin
These socks met my expectations as they are very thin and seem well made
United StatesExcellent socks!
I’ve experimented with lots of the leading socks in the realm and keep coming back to this model: my sensi skin likes the materials, the gauge or thickness works great for both my alpine boots and touring boots, and I’m impressed with their long lastingness and durability, too.
United StatesAlmost perfect
The socks fit very well in the toes and calf. Too tight at the top under the knee
United StatesBad fit
Bad fit totally useless Ordered extra large Could not get sock on either foot
FITS®
Hi John, Thanks for the review! FITS do fit snug to the foot and leg but you should be able to get them on your foot. Please reach out to help@fitssock.com and they can help with a return. Thanks!
United StatesUltra Light Teton Two Thumbs Up
I get plenty of warmth even with the Ultra Lights. On snowy cold days they keep my feet plenty warm in boots running errands around town. The graphics are so much fun it’s tempting to show a little leg when I am sitting down.
United StatesFits are my Favorite - 100% Recommend
These socks are great! As with all their products the fit is excellent(I wear XXL and FITS is one of the few that makes socks in my size), the quality is TOP notch and the 2 year warranty is such a winner. I buy multiples of everything and I've gotten rid of almost all of my other socks(as they fall apart) and the fits keep on going. I was destroying wool socks left and right and then bought some fits and they're still in essentially perfect condition. I will continue buying FITS for all my athletic and tactical pursuits.
United StatesAwesome sock
Perfect fit. Comfortable in my high performance ski boot.
