Liner - Crew
Nothing provides that extra layer of warmth when you need it most like the Liner sock. This ultra-thin sock is made of extra-fine Merino wool and won’t slip, slide, or bunch. All of the warmth without the bulk. A perfect mate to wear underneath your other FITS® for extra warmth.
- Dynamic Toe Cup® contours to the shape of your foot.
- Heel Lock® provides heel security that limits the chances of a blister when combined with a properly fit boot.
- Ultra lightweight flat-knit design.
- Double-welted top so the sock always stays up, doesn’t bind or slip.
- Crew height rises just below the calf.

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

United StatesWay too tight around leg
Nice fabric, arrived quickly but they r like heavy duty tight compression socks. If u have bird legs, not athletic/strong legs-these r perfect for u.
United StatesQuality has declined dramatically
The overall quality of Fits has decreased markedly. They feel like they're made with inferior product and do not fit the same at all. I wont be purchasing any more of these.
FITS®
Hello Margaret, Thanks for the review! I'm sorry you aren't happy with some of your recently purchased FITS. Please reach out to help@fitssock.com. They would be happy to discuss any concerns you have about the quality of the materials and production of our socks. Thank you!
United StatesBest socks for daily wear
FITS are so aptly named - they are feet-fitting, with no extra fabric to bunch up or abrade. I have 3 pair & rotate them to wear daily fall through spring. Perfection!
United StatesLINERS
THIN LINERS AND THICK HIKERS ARE THE WAY TO GO. THEY ARE PRICEY. THESE SOCKS DO THE JOB. I HOPE THEY GET SOFTER WITH WASHING, AS THEY SEEMED A LITTLE ROUGH THE FIRST TIME WORN. THEY ARE A VERY CLOSE FIT, STILL STRETCHY.
The best socks I have ever owned !
I switched from SmartWool to Fits several years ago when the store I usually bought the SW’s from was out and recommended the Fits. I felt the difference as soon as I put them on. The name is appropriate because the fit is incredible. The medium crew hiker is luxuriously soft, yet wears like iron. I wear them every day from Fall to Spring here in Michigan and get several years out of them. I would be lucky if a pair SW’s lasted through one. I recently discovered the Heavy Expedition boot sock and just ordered 4 more pair! I also love the fact that they are made here in the USA and that they offer Active Duty, Vets and First Responders a substantial discount. Thank you, Fits, for the most comfortable, supportive, durable, and just plain best socks I have ever owned!
FITS®
