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

Color, size, and sweat-wicking are fabulous. I wear them daily and they pair well with my Dansko clogs!

United StatesMy go-to socks!
I think I have 20 pair of FITS socks. And they're all my favorite. No blisters. No odor. Sweat wicking. Oh so comfy. I can't say enough good things.
United StatesLove the material. Love the color. Buying more in the future!!
United States United StatesThese are the best!
My new favorite socks. Threw away all my others as I always wear these. Super comfortable and wicking
United StatesThe best socks ever
I wear Fits socks everyday, because they are so comfortable and they are a must for someone with sweaty feet. My old socks would have my feet at a stink level strong enough to clear a room after a day's work. These have changed that problem in a major way. I walk around 6 or 7 miles a day and cycle almost daily, so these socks had their work cut out for them. Their performance has blown me away to the point where it is the only socks I wear.
