The ultimate combination: Merino wool for cold weather insulation and the performance that comes from a perfect fit. There is no other heavyweight sock that can make this claim. If there were, we would have made it! This sock is loaded with 100% Merino wool on the inside against your foot, so all you feel is comfortable and dry.
All our socks are made with 18.5m superfine weave, suit-grade performance Merino wool.
Our custom blend of man-made fibers selected for the best breathability and fit.
Excellent sock but they run small. Chart indicates that size large fits up to shoe size 10. I wear a size ten shoe and these socks are too small. You will need an Xl. Otherwise the warmth and comfort is fantastic. If you buy these socks you won’t be disappointed.
We love them! Everyone knows they get a pair each year for Christmas...and they’re always the favorite gift!!
I work outside and these are my go-to socks for the cold days. They are comfortable, not bulky, durable and warm. I love these socks!
My husband, a Production Manager, is on his feet most of the day on concrete floors. We have been looking for socks that have good cushion and warmth but will stay up in his work boots. I am happy to say that we have found it in the Heavy Expedition Boot socks!! He loves them because they do what they’re supposed to!! Great product!! I’ve already bought him a weeks worth and we will be looking at the summer line soon! Thank you for great socks!
Love my Fits Heavy expedition boot Socks -they keep my footsies Warm & Cozy all day on my Cold Wood Floors!!
FITS are some of the best socks that I have ever worn. These are warm and provide great cushion.
The heavy wool socks work well in my cool house. They come up to mid-calf which is another good feature.
The quality is good but the cost is just too high to have many more :(
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.
