Best Socks for Happy Feet

[This review was collected as part of a promotion.] Amazing socks that keep my feet dry and warm even in the warmest or coldest of temperatures. I never thought that a wool sock would be the best for my feet in the summertime, but I haven't wore a sock that performs nearly as well. #sweepstakes

Still the best

Size Bought:
M

I have VERY sweaty feet and live in SW VA, I wear these socks for everything, including all day at work on my feet, walking 18 holes of golf, and day-hiking the AT.

Very thick

Familiarity:
I returned this product before using it

As others have mentioned, these are quite thick and cushioned, especially for low-cut socks. If this is what you are looking for, definitely recommend! I was looking for something a bit lighter due to running in SoCal summer weather. I wear a women's 11 and I tried the L and XL. The latter fit me better.

Super Comfortable. Great Socks

I had been using thin wool running socks for hiking and was noticing my feet were getting very fatigued and sore. Switching to these socks has made all of the difference. It's amazing when you design something for a purpose, it works for that purpose.

Perfect socks!

These are my go to for running. I prefer the extra padding over the lighter styles. Also my go to for everything from hiking to the daily grind.

I would absolutely buy this product again

I purchased these for running because I normally like a little extra cushion, but then I also bought some running socks that I love. I'll use these for hiking. Super comfortable!

Great Socks

A little thicker than the running socks but perfect for longer periods outdoors and of course for hikes!

Definitely Recommend - if you like low-cut socks

[This review was collected as part of a promotion.] These are great. I wear primarily barefoot style shoes from Merrell, and these are a perfect fit for them. They are definitely low-cut, so be aware of that and make sure they will work with your shoes. The "Light" thickness has been a sweet spot for me, the Ultra Light socks were too thin and I wore through them easily, but I also wanted something that wasn't going to be super warm for all-year usage. #SmartwoolLove
