Your feet work hard, so make sure they're comfy. 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. Coffee is naturally odor-absorbing, so no more worrying about what your friends will think when you take off your shoes and kick back in your Loafer Hammock.

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.

dries ultra-fast

The material is constructed with microscopic pores which increase its surface area, so moisture is spread throughout the material and the drying process is accelerated.

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

Great socks!

Very comfy, durable and look sharp

Lots of Support

These are my favorite socks. They maintain that snug support to make my feet feel like they are being hugged all day. I just wish they were cheaper and wish they had ankle-high socks also.

Jeff Kavalin
Comfy and casual

A little hug but not so snug. Perfect !!

I love my Java Socks because they are comfortable and stylish! I equally love Java Socks because they’re made from recycled coffee grounds.
Please contact me with details of how I can involve my school district in donating coffee grounds.

Give me coalatree or give me…coffee?

These socks are as addictive as coffee. I went from skeptically trying one pair to now owning an entire week’s worth of these stylish incredibly comfy pair of earth friendly foot coverings. I have DVT in both legs so it’s imperative a sock fit over my calf but still allow me to pull them down a little while wearing shorts. They ain’t cheap but I don’t mind spending extra for such an earth friendly product.

Great feel

Great feel. Socks are a critical part of our outdoor gear/clothing. We also have purchased the trail pants which we love, and I have the puffy type jacket. I will continue to buy/support Coaltree as long as the products and support is good. We travel, camp, paddle, hike and bicycle. So far, so good. We live in the Southeast and are retired.
