Our hiking socks are made from a unique blend of cotton, recycled plastic bottles, and even recycled coffee grounds, so you can look good and feel good.

from cup to cloth

Spent coffee grounds are mixed and melted with recycled plastic bottles, then extruded into the fibers that create our Java Hiking Socks. The process requires minimal resources and utilizes sustainable technologies such as solar power, gray water recycling, and more.

Java socks

Had 2 pairs for a while They are very comfortable and fit well so I ordered more I have many coalatree products and enjoy them all

All around good sox

They fit my feet (long and narrow) nicely, but are not too tight at the top. The coffee fibers seem to wick pretty well. Nice smooth feel; no lumps around toes. I like them!


They’re very soft and comfy


Comfy and fun!

My new favourite socks!

I work at an animal sanctuary at the outskirts of San Diego. It's been cold. Snow on the ground cold. My regular cotton socks don't cut it, even with toe warmers! And with a wool allergy, I'm hesitant to try wool socks. I finally (!!) after many years of wearing Coalatree products, decided to try their socks. Yeah, I'm an eejit. Dunno why I didn't try these before. Maybe because the first sentence says "hiking socks?" These are not that. I wear these all day in steel-toed work boots at an animal sanctuary, and then the next day while walking around as a docent volunteer (same boots) at my local (world famous) zoo. Working socks. Not hiking socks. They keep my feet warm, dry, and they are oh-so-comfortable. I'm now color coded (green for the sanctuary, red for the zoo), and a couple of pair so I don't have to do laundry every week (more eco friendly, no?). (And yes, when I'm out at the sanctuary, I'm wearing a Baseline Midlayer under my eco-down jacket. This combo truly keeps me warm!

Dad raves about these socks and I have three pairs. Is it pronounced like Koala-tree or like a beverage Cola-tree? Thanks


Awesome socks!
