Warm, dry, love.
I love smartwool socks. These are great for winter everyday wear or hiking. Low cut and stylish.

I need more of these because I only have two pair but will run 6 days a week with them. They are so soft and thick, they'll add a half size to your foot though. But super comfy, I'll always take these for the long run.

Nice Thick sock! I throw these on with My salomon speedcross pro 2 and i can run for miles. They fill up any extra space in the shoe and they dont smell after runs. I am honestly going to buy a few more pairs of these to have on hand.

Comfy & Cushy
These socks are a great addition for anyone- my husband uses them for a variety of activities, including casual wear, going to the gym, and hiking. For being a lightweight sock, they certainly do have a lot of cushion to them- but he doesn't seem to care, as they are definitely comfortable. Just something to keep in mind- if you're looking for a very thin sock to fit in a tight shoe, I would go for something with a little less cushion.

Very cushioned for a light sock
These socks are super comfortable but are not as thin as I expected. They have a lot of cushioning built in. Great for hiking.

These socks are light but they are incredibly cushioned. With the elastic band around my arch, I feel extra support. The added lip makes it so they don’t fall down in my shoes, which is typically a big pet peeve for me.

Very freaking comfy!
I've been doing my laundry more often, just so I can experience the fantastic wonder that cradles my feet in merino wool. If you're giving these as a present, be prepared to accept the responsibilities of being the favorite.

Got these as a gift and they seem stretchy and pretty cushiony on the bottom!

Sweet light weight socks feels like nothing is there except all the comfort. Wicks away sweat like a breeze and there isn't unnecessary bulk from a seams that would get in the way. Love to wear things because I can throw any activity at them and they'll perform well!

I love everything smartwool makes and these socks are no exception. They are really comfortable and durable. I wear them casually and while hiking. The heel support is aweoome aswell!

Is it weird that I share my socks with my boyfriend? The sizing on this works awesome. I'm a size 7.5, he's a size 8. I fit perfect in the mediums. The heel support is unique and works great!

it's like a blanket for my feet!
Feels good, right size, and helped wick away sweat from my feet. Just jumped back online to grab a few more pair (for family and friends)

Great fit and feel
Perfect for everyday wear, running, or hiking. No seems in the toe area makes them super comfortable no matter what shoes you're wearing. These also have some cushioning along the bottom for added comfort when running, hiking or just lounging. Merino wool keeps them from getting too smelly. They hug your feet and stay in place preventing slippage along the heel and bunching underfoot.

My go to socks for any endeavor that doesn't require me to wear socks above my ankle. I can wear these for days on end without them smelling up the room.

Great wool socks!
I bought these for my wife and she was very skeptical at first. But after wearing them on a backpacking trip through Escalante she changed her mind completely! She loves these socks! They're warm and comfortable and for her... the best thing is they retain their shape whether wet or dry.

I really like these socks. They are thin, keep my feet cool and dry, the material is comfortable, and they have cool patterns. The tab in the back is a nice addition as well.

I purchased these for my husband and he loves them. They are comfortable and time will tell if they are durable. Good quality socks.

My go to backpacking socks
I wear these things everywhere but where they really shine is out on a backpacking trip. I'll bring two pairs for a week long backpacking trip and they never get disgusting enough to where I don't want to put them on my feet.

Love these socks! Feel so light on your feet and keeps them cool and dry. My feet are always hot and these socks make them feel great
