      Best ski socks

      Second pair of ski shocks I bought from Fits. These things are great and feel like new season after season. These are the must have thin sock if you have custom boots and liners

      Ultra Light Ski (Teton) - OTC

      I recently started getting into some bad wool toe abrasion from two other top name wool sock brands which I always loved. These socks were recommended to me by my niece who lives a similar lifestyle out in the ski areas and often has some cold feet. I am thrilled with these socks. No to rub due to a perfect "fit". Longer space for the big toe and the material is great.

      The heels

      My fits socks feel great. They are comfortable. They look good. I really like them. My one issue is the heels, and the color from the yarn/material wears out faster than I would like. I don’t want the real thick skier- type sock but is there anyway to address the heel issue?

      Fly fishing

      Loved them! Cold, wet weather of the river and my feet stayed warm all day long. These will be my next ski socks as well.

      I bought these socks for my mom who is diabetic and has neuropathy. Most socks hurt her feet but she loves these. They don't hurt her feet or legs at all. Would recommend!

      Great Motorcycle Socks

      I bought the Ultra Light Ski socks to wear with my motocross boots. I had been wearing medium weight OTC Fits socks, but my feet kept getting hot and sweaty. The Ultra Light OTC Ski socks work great, and don’t fall down during hard off-road riding. Time to order a few additional pairs for my next long distance ride.

      Best socks

      I gifted my husband these when he had ankle pain and some swelling. They worked the best of all he tried.

      Great socks.

      Great thin ski sock! I work ski patrol; they are the only socks I wear. Never thought socks would be something I'd be so enthused about but never realized the difference a Great fitting sock could make.



      The Perfect Fit Starts With the Right Size.

      Your sock size shouldn’t be a guessing game. Our socks range from small to double XL, but the best way to know the perfect fit for you is to match your shoe size to the chart on the left. That way, you’ll know the size you select will give you the fit and feel you expect.

      Between sizes? Go with your gut, but rest assured that your socks will still fit great. If you receive your order and find yourself wishing you’d gone up or down a size, just let us know. We’ll happily send you replacements for your preferred size.

      Concerned about laundry mix-ups? All FITS® socks are coordinated by color and size, based on the colors you see on the size chart. So, you won’t have to worry about mixing up your sizes with the other FITS® wearers in your home. (But stray socks mysteriously going missing in the dryer? Unfortunately, we can’t help with that.)

      Questions? Let’s talk.
