Beefy in personality, versatile in form, Darn Tough's cushy Mountaineering sock makes the most of big summit efforts and down day energy in a Heavyweight Micro Crew. Full-wrap cushion around the footbed and all-over Merino offer warm, lounge-worthy comfort akin to your favorite house slippers but with the proven, long-wear durability to explore beyond your comfort zone (and laundry basket) for weeks on end.

Darn Tough's warmest socks - heavyweight socks regulate heat, transfer moisture, and provide steady comfort in cold weather. Merino Wool is at home on the trail, naturally moving moisture to keep feet fresh and dry in all weather.

A performance fit means no slipping, no bunching, no blisters for peak hiking comfort. The reinforced Achilles cushion improves the comfort of the socks and helps them last longer.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
