      I have been trying a few different styles for my steel toed work boots. These work great and stay up.

      Best ski socks!

      This is my second pair of FITS and it won't be my last. I've purchased ski socks from a variety of manufacturers and the FITS Ultra Lights are my faves! They fit snugly on my feet and never give me any uncomfortable, inadvertent "sock wrinkles" which has happened with other ski socks. They work well with my tight-fitting high-performance ski boots.

      Perfect for spring skiing or hiking

      Great fit (true to sizing guides they post) and top quality socks. These are a little lighter weight than the others and are good for warmer weather and other springtime activities. I've bought several different styles from FITS and all have been comfortable, sized right and excellent quality.

      Fit well and perform well,

      Fit well and perform well, even in very cold weather. Eliminates bunching, and has some wool in the blend which helps with warmth.

      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.
