I love, love, love these sox. When first putting them on, they felt a little less soft than my other medium Fits (medium hikers) but these keep my feet warmer in our Minnesota winter! Could it be due to the loop material on the inside providing for more trapped warm air? Whatever it is, I’ll be looking to add more of this sock to my collection!
I ordered these for myself & they are so strong, soft inside, textured outside. I wore them for 3 days straight & they never lost shape! I wish I'd ordered more pairs!!!
Love the socks, definitely warm. I have raynauds syndrome so I need warm socks.
Super warm and comfortable socks with just the right amount of compression on the calf and excellent cushioning throughout
I always have freezing feet and these socks kept my feet warm from morning til night...for 3 straight days! I had read another review by someone who said they got 3 wears out of their socks before washing, so I gave that a try too! I couldn’t believe it, but even by the end of the 3rd day I couldn’t smell anything from the socks, which is absolutely not normal for me! These are wonderful!
Great fit and compression!
I love this sock! I love FITS! I don’t buy any other socks!
I needed a thicker, plusher sock to fill out a looser-fitting hiking boot for extended day use. Having used Fits medium thickness socks for years (none have worn out) i got the ruggeds. These socks are really plush and fill a shoe. You would have to get the tactical or expedition grade sock for anything heavier. Just watch out you dont have too small a shoe to use with it.
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.
