Heavy Bison Work Sock

The Heavy Bison Wool Work Sock is the ultimate cold-weather work sock. 

Made with a 70% Bison-Merino wool blend, this full-cushion terry loop sock offers the relentless insulating power of American Bison combined with the comfort and cushion of our Ironside Merino wool. 

Steel toe boots in freezing weather can feel ruthlessly cold. Now, with our Heavy Bison, you can finally get relief for your cold toes. 

With heavy wool padding on the toe, heel, and through the calf, these socks offer all-day comfort and a hefty layer of protection for your feet. 

Bison + Ironside Durability

Made with 70% Bison + Ironside Merino wool that puts regular socks to shame. We’re so confident in our socks, we offer our Decade Guarantee. Work in your socks for 10 years and if they get holes, send ‘em back and we’ll replace ‘em. 

Cold Weather Comfort

Our high density knit Bison wool blend helps keep your toes warm in the winter. These socks are meant for brutal winters. American Bison are adapted to the coldest northern conditions, and so is our Heavy Bison sock. 

The wool blend here wicks moisture away from your feet so they stay dry, warm, and comfortable.

No Sweat Vent

The natural fiber in our socks vents sweat and moisture away from your foot, which not only keeps you more comfortable, but prevents blisters and reduces odor. 

Plus, we add our signature No-Sweat Vent to the top of the foot to keep moisture down so that your socks stay dry, even during a 14-hour shift. 

Compression and Support

We weave Spandex and nylon into our fabric to create light compression around the arch of your foot. The compression helps circulation, which helps your recovery time so your feet still feel fresh the day after putting in 14 hours on the job site. 

USA Made

Our socks are made in North Carolina with US wool.
