Benefits of Merino Wool
Moisture Wicking
Merino wool is the best fiber to regulate moisture. It does this by absorbing sweat from your skin and releasing it into the air. Whether you're hiking, running, biking, on the job, or just relaxing at home, our wool helps keep you dry and comfortable all day long.
Soft & Comfortable
Merino wool fibers are much finer than traditional wool, creating a luxuriously soft feel that won’t itch or irritate your skin. Comfortable enough for everyday wear and gentle enough for sensitive skin, it’s a natural choice for underwear, base layers and next-to-skin comfort.
Highly Breathable
Merino wool’s unique structure allows air to circulate freely, helping to regulate your body temperature in both hot and cold weather conditions. Whether you're layering up for winter or staying cool in summer, Merino keeps you comfortable by letting your skin breathe.
Anti-Microbial
Merino wool naturally resists odor-causing bacteria, keeping you fresher for longer. No lingering smells, even after extended wear. Perfect for travel, outdoor adventures, and everyday life.
Insulates When Wet
Merino wool can hold up to 30% of its weight in moisture without feeling wet or clammy against the skin. Unlike cotton or synthetic fabrics, it keeps insulating when damp, making it a smart choice for unpredictable weather and high-output activity.
Fire Resistant
Merino wool is naturally fire-resistant and self-extinguishing. It will not melt or stick to your skin like synthetic fabrics. A trusted option for first responders, campfire safety, or any high-heat environment.
UV Protection
Our Merino wool clothing helps protect you from the sun’s harmful rays, with different levels of UPF based on fabric weight:
-
Microweight (145 GSM): UPF 20
-
Lightweight (170 GSM): UPF 25
-
Midweight (245 GSM): UPF 50+
-
Heavyweight (400 GSM): UPF 50+
These natural UV-blocking properties make Merino wool ideal for long days or the beach or above treeline.
Renewable and Sustainable
Merino wool is a natural, biodegradable fiber with a low environmental footprint. Grown by Australian Merino sheep and shorn seasonally, it is a renewable material that supports responsible farming practices.

I purchased these socks at a discount through their pro program.
I was surprised to see these are 100% Merino wool, some other makers have a blend of materials for stretchiness and such but these are nice and stretchy without any of that. The microweight does seem to have slightly less stretch than the lightweight ones I also bought, just a smidge tighter around the calf, but not uncomfortably so; I bought the XL size because I have larger feet (US size 12.5-13), and these seem to fit nicely, definitely better than most big-store options that either only go to size 12 or are still just very tight at their "big and tall" sizes. Tiny bit more stretchiness would make these perfect for me but that's a personal preference.
They've become my everyday around-the-house socks now, the cushioning is great for cold floors without the rest of the sock being too warm; in fact they're even a bit cold right now in the Northeastern winter, so I'm excited about being able to wear these in other seasons as well!
I can buy a multi-pack of department store socks for less than the price of a single pair of these, but I can also wear holes in that whole pack of socks in the span of about a year; we'll see long-term how these hold up but it's immediately apparent that these are much more durable, so in the long run I think it's a much better value to invest in nicer socks like these ones rather than just going through packages of "disposable" socks.
They fit well and feel like they are going to last
- They go right up to the knee and they don't fall down at all. They're warm and cozy.
- They stay up all day, which is most desirable. Very comfortable and very thin.
- Well made and will last a long time. American made exceptional socks.

Fast shipping and the socks are awesome. They’re longer than I thought, and I’m a size 13 with pretty muscular calves. They go right up to the crease of my knee. They also stay up all day, which is most desirable. Very comfortable and very thin- thru dont make my feet sweat nor do thry smell at the end of the day.

I don't know why, but my feet nowadays just stay cold. I am 73 years old; maybe that is a part of it. But I have been looking for socks that could keep my feet warm. It has been a while, but when I got my hands on the MINUS 33 socks, my shopping for socks was over. They are the best socks I have found.
John,

We understand the struggle of finding the perfect socks and we are glad that our MINUS 33 socks have met your expectations. Thank you for choosing our product and we hope they continue to keep your feet cozy.
Jeannie T.
My feet are cold almost year round. These are the best perfect fitting warm socks I have ever purchased. So glad I was introduced to minus33 company by Wildkind Academy.
Laura,
Thank you for the review! We're glad to hear that our socks are finally warming your feet up!
-Minus33
These socks are great under boots or shoes, and keep my feet toasty. I have some lipedema, so my calves and legs are big and most socks will cut off my circulation. These are long enough to get to a natural place just at the knee. I will have to take care they don't get into the dryer and shrink, which would be sad for me. Love these also for a trip we are taking to a rainy climate.
Alison,
Thank you for your review of the Mountain Heritage Over the Calf Wool Socks - Full Cushion. We're glad to hear that they work well for you and keep your feet warm and comfortable. We hope you have a great trip!
-Jeannie T.
These are the best everyday sock I’ve worn. They wear like heavier socks both warmth and comfort but not bulky. I have a drawer full of other brand wool socks that need to be made into sock monkeys! Thanks for a great product!
Scott,
Thanks for the great review! We're glad you're enjoying the new Mountain Heritage Over the Calf Wool Socks - Full Cushion.
-Jeannie T.
Great
Best socks ever. Slowly replacing everything else with these. They work well as compression socks too.
TM,
Thank you for choosing Minus33 and for leaving us such a great review on the Mountain Heritage Full Cushion Over The Calf Wool Socks. I am also in the middle replacing all of my socks with merino wool! Thanks again for taking the time to leave us a review.
Stay Warm,
-Steven D
Super warm and very comfortable
I have tried SO many wool socks over the years, and these are my favorite. They go right up to the knee and they don't fall down at all. They're warm and cozy, and I love that they are made in the USA. My whole family are going to be getting these for the holidays this year.
Renee,
Yes, our Mountain Heritage Over the Calf Wool Socks are very warm and cozy. We are so happy to hear these socks are your favorite! Socks are a great gift.
Thank you for the great review!
-Jeannie T.
I love these socks, they keep my feet dry and cool in the Florida Heat and Humidity. Love them.
Tracy, thank you for letting us know! There's a common misconception that wools only good for the cold, but its wonderful at keeping you cool in the summer. -Felicia W.
I wear a pair of these socks every day. They’ve spoiled me, and now I don’t want to wear anything else. I wear them to work. I wear them to hike. I even wear them when I go to sleep because I hate to have cold feet.
Heather, thank you for taking the time to leave a review! We're so glad you love your socks, and even happier that we can be your new go to! -Felicia W.
I have had them for a couple months now, these are great socks!
I wear Minus 33 layers from head to toe. Love it all. More affordable than a lot of brands and stands up great. The socks are probably my favourite. Use for split boarding, boarding at the hill, hiking, snow shoeing and other every day stuff. Have tried other big name socks and they are garbage in comparison. Always dry, warm and no stink. Will definitely buy more Minus 33 stuff in the future if I can manage to wear out what I got.
I bought these as a gift for my son for Christmas. He hasn’t received them yet so I can’t give you a review. However, placing my order, speaking with a friendly employee, getting my order in a timely manner was pleasant!
Thank you for sharing your experiences!
