Clays should fit snug, even tight at first as they will stretch. They will β€œbreak in” and take the shape of your feet within days to a few weeks depending on frequency of wear.

If you are between sizes, we recommend sizing up, especially if you intend to wear the shoes with socks.

Copper is highly conductive, durable and antimicrobial and is attributed with many health benefits. The copper rivet we use in our shoes acts as a conductor of electron flow from the earth to your body through the soles of your feet. Our unique leather sole allows for increased conductivity. The moisture of the outdoors and perspiration from your feet will increase the sole’s conductivity over time, making your leather soled Groundz the ideal grounding shoe.


"Zero-drop" non-elevated heel for proper posture, and a safer, more natural gait. No arch support to strengthen foot over time. Minimal naturally molding sole for added comfort without compromising foot stability. Feel the ground.


We have designed our shoes specifically with the natural shape of the foot in mind. A wide toe box lets your toes spread, grip better and relax when needed. Barefoot shoes that are foot friendly and foot shaped!


We use natural materials throughout - Sustainably sourced Eco-friendly leather dyed using chrome-free, water based and nontoxic vegetable dyes; Natural clay adhesive instead of synthetic glues and beeswax soaked cotton thread tying it all together. Respectful to the environment and to the health of the wearer.

Amazing quality, it didn’t work for me to stand on the stitching

Super soft leather, really lovely and well-made shoe. I usually wear a womens US 9.5 or EU 40 for a shoe that I won’t wear socks. My feet are 10cm wide, and around 25.5cm long, and high volume, narrow heel. These in size 10 were too short - my toes were tapping the inside of them. They fit in width and volume perfectly. I considered sizing up, but conceded an 11 would be too big if the leather stretches. I also have sensitive skin and it was too much texture for me to be standing on top of the lacing inside the footbed. I could wear socks or add insole but wondered if that could interrupt the grounding feature. Definitely would try these again in the future if the stitching issue changed! It was easy to return them.

Comfy Casual clays

I recently received my first pair of Groundz Casual Clays after shopping for an earthing shoe of ALL natural material made in the USA. I am pleased with the craftsmanship, service, and comfort of my casual clays. So much so, I ordered a pair for my sister. My wish is for all who are interested in the value of such shoes to learn about Groundz Shoes and to get a pair to experience!
