The answer - nothing. These are cozy, they fit well, are quality and will definitely last.

I stumbled across these socks at some point and fell in love with them. Nowadays I refuse to hike in any other sock. Test these socks to the limit and you won't be disappointed. They form to the foot so well and the toe seam is basically nonexistent. With other popular wool socks there would always be an excess of material that would bunch up at the toes and the heel. The lifetime warranty is an added bonus.

Great product, the only hiking socks I use and recommend!

What can I say. Comfy, durable socks. They are Darn Tough top of the line.

I have the Men's version and I'm a big fan, so naturally I had to get my wife a pair so she could see what the hype was all about. Well...4 pairs later, it's safe to say that she's crazy about them!

I buy these over and over again for hiking and backpacking. Nothing can beat them! Cushion where you need it, wool wicks moisture and odor, and they stay put and last for endless re-uses.

I gave these to one of my friends and she has used them for several multi day backpacking trips and loves them

I used these socks for backpacking, and was very impressed. I like my socks a bit on the thinner side typically, and was a bit worried about the cushion in these, but instead of feeling bulky these just felt comfortable!

These socks are great for hiking and are very comfortable. Will definitely buy again.

Love everything about these. Extremely comfortable and have already withstood many backpacking adventures. Worth every penny

Can’t say enough good things about Darn tough socks. Very comfortable, breathable and durable. Have worn these on many hikes and they’re as good as new.

Quote from my girlfriend- "These socks are super comfy. I love hiking in them because it feels like I am stepping on little cushions. I am a size 8.5 and got the mediums, but they seems a little large. However, I just wear them pulled up pretty far and they do a great job. These are definitely my go to socks for hiking and every day."

After buying my first pair of Darn Tough socks a few years ago, I won't buy any other brand of hiking socks! I have four pairs that I rotate through and they have not shown any signs of wear. They're so comfortable for any activity, whether it be long days of yardwork or hiking. They don't bunch up in your shoe or fall down. This particular sock though will definitely keep you warm. Too thick for my taste if I'm trying to wear it on a summer hike but perfect for chilly days. My Smartwool socks don't even compare to the excellent quality of Darn Tough!

My opinion: Wash & use softener before wearing. More comfortable & less skin irritations (if sensi skin like me). Super nice though after a few washes for me. Used on 6 day hiking trip!

I love these socks. Durable and comfy, they're my go-tos for any hiking trips these days :]

These Darn Tough socks are the best! Kept my feet in great shape while in Peru for 3 weeks....including a 4 day Inca Trail Trek with 2 days of rain.

I've worn these socks a ton, warm weather, cool weather, doesn't matter. These socks are killer! And with a lifetime warranty, can't go wrong!

After reading lots of reviews and hearing about Darn Tough socks from my friends, I finally decided to get myself a few pairs. I wore them for the first time on a 15 mile hike. They're comfortable and well-made, and I like that they have a lifetime warranty. Perfect as a gift to yourself or for friends.

I love Darn Tough socks more than any other socks! They're super cush and my feet are happy wearing them! Even after 10-12 hours in them! Best socks ever! I wear a size 9 shoe and the Medium socks fit perfectly.

My girlfriend was asking for some new work socks and I ordered these for her. She raves about them! She blows through her Smartwool socks so fast with just normal use something tougher was needed.

She has 8 pairs now and has worn them for work everyday for the past month. Even on days getting up close to 100 degrees in work boots she says her feet stay more comfortable and drier with these socks than any other. Cold mornings getting down to around 30 degrees she has worn them with just her Chacos and (surprisingly) had no complaints of cold feet. These socks make for happy feet!

Bought these for my girlfriend and she loves them. They have great cushioning and they keep your feet warm and dry. The durability and comfort are unbeatable.
