Free ReturnsThe Ultra Light Ski helps you push the limits while limiting the amount of material in your boot. Our minimalist's Ultra Light ski sock uses super-fine Merino wool and its natural ability to manage moisture and regulate temperature. The Ultra Light Ski has minimal cushioning and is best paired with custom or very close-fitting boots, as there is little material to pack out the inside of your boot. The Ultra Light Ski features a vented foot top, as well as proper gradient compression throughout the leg and over the calf, stimulating blood flow and keeping your legs feeling invigorated for as long as you wear them.

United StatesI’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 StatesThe socks fit very well in the toes and calf. Too tight at the top under the knee
United StatesBad fit totally useless Ordered extra large Could not get sock on either foot
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 StatesI 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 StatesThese 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 StatesPerfect fit. Comfortable in my high performance ski boot.
United StatesI have always loved my FITS! I bought them by accident, but it turned out to be for the best. They are so thin yet surprisingly warm. I have very stiff and very tight boots (racing style), so I can't fit much in them. Couldn't recommend them enough!
United StatesThese socks were great for skiing. Warm but not too thick.
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.)
Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you.
To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart.
The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you.
Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:
Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot.
Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.
