Frequently Asked Questions

What size should I get?

Men's sizes follow your US shoe size: Small fits 3 to 5.5, Medium fits 6 to 8.5, Large fits 9 to 11.5, and X-Large fits 12 to 14.5. If you're between sizes, size down, since the merino and spandex blend stretches for a snug fit. If you have wide or high-volume feet, size up. See the full size guide.

Which cushion is best for running?

Ultralight has no cushion, just a thin knit, so it's our coolest running sock. It's best for racing, hot-weather runs and snug, fast shoes. For a little protection underfoot, Light Cushion is our best everyday running sock. For long trail runs, rocky ground and cold mornings, try Medium Cushion, as long as your shoes have room. Our cushion guide compares all three.

How high does a 1/4 top sock come up?

It sits just above the ankle, so it covers the ankle bone and keeps trail grit out of your shoes. For less coverage on the road, try our No-Show running socks.

Will these help prevent blisters?

Fit matters more than thickness. Blisters come from friction and moisture, so a sock that stays put and doesn't crowd your shoe helps most. Merino wicks sweat to keep feet drier, and the thin ultralight knit leaves the most room in snug shoes. Try your running shoes on with the socks you'll wear.

How should I wash them?

Turn them inside out, machine wash cold or warm with like colors, and tumble dry on low to warm heat. Skip bleach and fabric softener, because softener can reduce wicking. Every sock is preshrunk, but high heat can still shrink wool over time. Full tips are in our washing guide.

What does the lifetime guarantee cover?

If your socks ever get a hole, or your dog eats your favorite pair, send us the guarantee form with your order number, or the name and email you ordered with. Our in-house team will replace them.

Why isn't the merino percentage 80% if the yarn is 80% merino?

Every Cloudline sock is knit from the same yarn: 80% RWS certified merino wool and 20% nylon. The nylon makes the yarn much more durable, since 100% merino wears through quickly. The fiber content on each sock also counts the nylon reinforcement and the spandex that keeps the fit snug. That's why the merino percentage changes a little from style to style.

Compare running sock cushion levels

Every pair is knit in Fort Payne, Alabama from the same yarn: 80% RWS certified merino and 20% nylon for durability. Fiber content shifts with the cushion, reinforcement and stretch, so pick the padding that fits your shoes and season.

Why merino wool socks?

Cool in heat, warm in cold

Merino adapts to your effort and the weather, so one sock works from desert miles to winter trails.

Dry feet, fewer blisters

It wicks sweat away from skin, which is why it works for sweaty feet and long days in boots.

Naturally odor resistant

No chemicals or metals added. Kick your shoes off at the end of the day with confidence.

Soft, not itchy

Fine-gauge merino yarn feels nothing like the scratchy wool socks you remember.

Great socks, not just for outdoor and hiking, but for all around use. I wish they made wool underwear as well.

Perfect gift for my husband

My husband is super hard on his socks. Usually a pair only lasts him a couple weeks before they get holes in them. I came across cloudline and their warranty so I decided to get him some for Christmas last year, and they’ve worked out perfectly for him. After a year of use, there’s still no signs of wear. I’ve placed multiple orders now to start to replace all his socks with cloudline. Was hesitant about the price at first, but the quality is definitely worth the investment and I feel confident (even without the lifetime warranty) that these socks will hold up for quite awhile.

Great everyday socks!

These are great everyday socks with perfect height. They are not too loose and not too snug. Unlike other socks, these socks actually don't smell after a whole day of wearing. The minor complaint is that the elastic at the top of ankle can be a bit tighter.

These socks have lasted 2

These socks have lasted 2 years of regular running and everyday use. I trained for a full marathon using these socks year and they show every little signs of wear. Fully recommend.

My only socks

I’ve worn these exclusively for about 5 years. Do yourself a favor and ditch all the old mismatched oddball stretched out stuff from your sock drawer and order up from cloudline!

Not very comfortable or soft at all. A bit stiff. Regretful purchase.

High Quality Comfort

A 3 pack of these socks, bought 3 years ago, has outlasted 6, 6 packs of Costco socks, that I have purchased in the past 3 years to cover me when my 3 pairs of cloud line are out on loan to my wife and daughter. I finally realized that quality is better than quantity and got all of us cloud line socks for early Christmas and we have been happier and kinder since then...

these are the only socks

got my first pair a few years ago, have worn them hundreds of times, and other than a bit of (predicable and unavoidable for merino) piling, they're good and strong as new.

Best socks ever!!!

These socks are great! They are very comfortable, keep feet dry and warm, but not too warm. I highly, highly recommend them!

Very good for high-wool content sock, but can't compare to specialized running socks

I think this is as good as it gets for socks with such high wool content. Deserves 5 stars as wool socks and I'll buy more. They do not smell even after multiple wearings. I got caught in cold winter rain on 2 runs and they performed excellent. I took off one point because they're recommended for running. To me, these socks are a bit too loose and sloppy for serious running. You can size down (I'm a 9.5, 10.5 in running shoes and bought the LG) but without a lot more nylon, I don't think they're elastic enough to hole on tight to the feet. I own other running socks (including fox river and darn tough) and they're a lot more tight and compressive. Also, be aware that this isn't really ultra-thin like the darn tough ultra lights. They're equivalent to the thin darn tough and fox river socks.

Great for Summer hiking!

Used these on numerous hikes this last summer. When I wanted to wear a sock in the summer this is what I picked. I've also been using on this fall. I'll just say like all my cloud line socks, they're great!

Comfortable and no stink feet! I know I keep saying that, lol

So I have been trying out the various weights and styles of these and the Ultralight turned out to be perfect for the summer in the desert and with some of the shoes I wear at the races and events. The lightweight & mid-weight have been the go-to's when we are out in the dirt & sand with hiking shoes.

Perfect Socks

I ordered these socks because I have very sweaty feet. These socks are breathable and have no signs of my foot odor either. I highly recommend.

Excellent Activewear socks.

Wonderful socks; super comfortable for all kinds of activities, and not a think pile, but not super thin either. The merino really makes a difference. These are excellent. I hope that Cloudline will source 100% of the material from the USA - that would make them perfect.

Tyler M.
Great socks and would recommend for the price.

These are great socks for the price. They don't shrink too much when washed which is nice for people like me who don't want to worry about separating them out in every wash. They soften up over time, but still aren't quite as soft as some of the more expensive brands I've used. However, for the price I am very happy. They breathe very well, dry quickly, and don't get stinky. I wish they were a 1/2 or so taller above the ankle, but I'm 6'4" and I'm sure they are perfect for most people.

Held up through a 10-miler

I wore these through a 10 mile trail race and they helped keep my feet cool and dry. As promised, there was no cushion on them, so comfort kind of depends on the shoe you wear with them. There is something to be said about staying I place on your foot, though. I don’t ever have to adjust them.
So far, I haven’t had any holes or visible wear on them, so that’s kind of impressive, too.

Five stars for being exactly as advertised.

Buy Some!

Really comfortable and great fitting socks. I especially like the over the ankle fit. The different levels of cushion from ultra-light, light, and medium are nice to be able to choose from for a particular activity or type of shoe.

Gotta Love Those Cloudline Socks

I'm loving Cloudline socks! I actually use these for cycling, on the trainer at least. They are perfect and once the weather warms up they will be used outside on the bike. I'm slowly changing all my socks out Cloudline I like them that much!

Great socks

I wanted good Merlin wool socks to replace some worn out ones. These are great and the BOGO half off deal was the ticket. Light yet warm and comfy. 2 thumbs up on these socks.
