As many of you keep telling us, our Sleep Socks are one of our favorite products, ever.
The sleep sock was designed to leave unrestricted circulation around the cuff - a top rising softly just above the ankle with no extra spandex ... just the natural stretch of the terry loop construction. It adds the needed insulation to keep your blood supply in the feet comfy in bed, walking, or even with shoes or slippers. This version of the sleep sock is a yak/nylon yarn blend.
Slipping into a cozy pair of ultra-soft, wicking, comfortable, natural fiber sleep socks after a long day can be one of the most luxurious feelings. Not only do they help regulate body temperature by wicking away moisture, but socks made with natural fibers can also help prevent odors and fungal infections, making them a great choice for those with sensitive skin. Additionally, the softness and breathability of these socks can help promote a more restful night's sleep, as they won't irritate or constrict the feet.
They are warm, comfortable, and durable and we have it on good authority that they actually saved several marriages.
Features:
- Next round of production will be spring of 2026, limited sizes available at this time.
- Stretch terry loop construction on inside, flat knit outside
- Loose cuff bind off the top of the sock, less restriction on the ankle
- Natural brown Yak fiber (no dyes)
- Imported yarn
- Knitted in USA

Here at The Buffalo Wool Co., our yarn bases for all our gear is (and will always be) natural fibers. This means that the internal structure of your socks (the parts that touch your skin) will be made from bison fiber, merino wool, mulberry silk, and other 100% natural fibers.
The overall composition (the parts that touch your skin plus everything else) will include other materials like nylon or polyester. This is done to make the sock more durable and ensure that your socks work (and play) as hard as you do.

They are warm and comfortable. After I washed them as directed in cold water and let them dry on my small drying rack, the pilling was terrible. Photo attached.

We love them so much we hoard extra pairs for the future
D
I absolutely love these sleep socks. They are very soft and I look forward to putting them on every evening. They keep my feet at a perfect temperature. I even wear them under my wool slippers and my feet still don’t get hot. They also stay in place on my feet really well. And I kick around a lot. I absolutely intend to have these on my feet every night for years to come. I plan on trying the trekkers next. See how they do in the winter.

I can often overheat with thick socks on. But these keep me warm without being a heat casualty. Comfortable and functional. Wife and I each wear them regularly!
M
I opened the socks and was a bit upset because I did not like the color, but I decided to try them anyway and I’m glad I did. They are the warmest I’ve ever owned - and that includes alpaca wool and cashmere blend. I love these socks!
C
I've had a problem with tight elastic around my ankles for years. I've tried to find looser socks with no success. They either end up too big in the foot or super low quality. These 'sleep socks' are sweet! Not too tight around my fat ankles. They don't squeeze my legs and cause my restless legs to flair up. I'm about to go buy a second pair right now.
All around these are quality socks. Kinda thick, but not too bulky to go inside a slipper. I've only worn them around the house for a week - 2 washings and they are holding up well.

Very comfortable..

You don't have to just use them for bedtime: they're nice and cozy
K
100% worth the price, I bought one pair and then 6 more. Finally my feet aren’t freezing anymore! And they aren’t clammy either, I’ll be buying these the rest of my life!

Keep my feet war and comfortable all night long,

Very comfortable

I hope I can pass on to the Buffalo Wool customers the same happiness that my friend received from the gift of soft, warm socks that we sent him after he had to have his toes removed from one foot. Thanks for a great product.
L
Soft, extremely comfortable and the perfect thickness.
B
My husband loves them, keep his feet warm in this chilly environment.
R
The wife loves em. Mission accomplished.
G
A medical condition keeps my feet feeling icy almost all the time. The sleep socks have truly been an answer to a maiden's (albeit an old maiden) prayer. They help me get to sleep and stay asleep better than any cotton or wool I've tried before.
H
These are indeed my favorite socks I own. I had to buy my husband his own pair because he loved mine so much. I highly recommend it to everyone I know. I Love to use them to sleep, but I also use them to work too!
P
Immediately upon putting on these socks I felt my feet warming up. Within minutes they are warm and cozy, and I’m drifting off to sleep. I’ll be buying more for gifts!
J
I love my sleep socks. Totally wonderful. My son happened to mention his feet got cold and when he went to bed he would use a heating pad on a timer. So...I purchased sleep socks for him. And guess what. He loves them and no longer uses the heating pad. If my socks ever wear out...no sign of that at all...I will immediately purchase myself a new set. Jim in Alaska.

Great Product/s! I had already purchased the socks: tall ones, short ones, etc. I needed the sleep ones once I saw that they were offered. I highly recommend all of these products and I love my socks and beanies! Great Products!!!

I got these for my grandmother who is 104, has swollen feet, and is always cold. She said she likes them, and that is quite a compliment from her.
A
first of all i wear the sleep socks at night when watching tv,they are comfortable and easy to put on,secondly they are of excellent quality but i do wear a heavier buffalo sock during colder weather.
M
My husband will not go to bed without them! We both love them. They are so soft, cuddly and warm.
C
Just perfect! Comfortable and not tight!
J
I bought these for my husband and he loves them. He doesn’t wear them as a sleep sock, he wears them as his everyday sock. I’m sure he will be asking me to get him another pair soon.
A
Wife is very happy with these. No longer has to change socks throughout the day. Thank you!
A
Got them for my wife and she loves them.

I absolutely LOVE these socks. They’re cozy and comfortable. Thick enough that I wear them instead of slippers.

Content is good. Keeps my feet warm .
