The best
You walk every day. These BioTime Earthing Sandals make it easy to stay naturally connected to the Earth while you do it, combining everyday comfort with a simple conductive design. A copper rivet runs through the sole, creating a conductive pathway between your foot and the ground beneath you. Step onto a conductive natural surface and the rivet helps maintain direct electrical contact with the Earth.
Designed for more than grounding, these sandals feature a contoured cork footbed that supports your foot's natural shape, plus adjustable straps for a comfortable, personalized fit.

Real experiences from customers wearing our BioTime earthing sandals.
“Fit perfectly! Quality appears to be well made. Arrived quickly and well packaged, as usual.”
“I was concerned before purchase that having a rivet near the arch of my foot for connectivity to ground might cause them to be uncomfortable. But, a lengthy walk outdoors in them showed them to be quite comfortable.”
— Merle W. May 15, 2024“This is a well built sandal. I have been wearing only these for the past two months.”
“They are comfortable, great looking, wear well and knowing that I am grounding at all times when outside... That’s the cherry on top.”
— Sharon V. July 10, 2023“I received my sandals yesterday and they are the perfect fit. I bought a men's size 7 because I wear a women's size 9.”
“They are very comfortable and look nice too. Great price and product. Would definitely recommend!”

Published studies suggest grounding may help reduce inflammation, ease pain, and support better sleep — by allowing the body to absorb the Earth's natural electrons.

You can now enjoy the health benefits of Earthing while still wearing sandals with a rubber sole, thanks to this modified sandal with a copper plug/rivet. These slip-on sandals have an 8 mm soft EVA outsole and a copper plug inserted into the sole. Copper is a conductive material that allows electron flow to pass through to your skin. You can now enjoy Earthing with every step you take, in the spring and summer.
These men's earthing sandals have an artificial upper in brown, black, or taupe suede for a casual look. The upper features a double adjustable strap for the perfect fit. They have a Biofresh-covered, contoured cork footbed that is suede-covered and provides unsurpassed orthopedic comfort and support. These sandals are not only for earthing, but may also help minimize discomfort from plantar fasciitis, bunions, diabetic foot problems, and other foot pain. They come in EURO sizes 40 - 45. These men's sandals are made in Spain, and we personally insert the copper rivet in Canada.
Grounding restores direct contact with the Earth, something modern footwear often prevents. Research into grounding has explored potential effects on sleep, stress, inflammation, circulation and recovery. Earthing footwear offers a simple way to incorporate that connection into time spent outdoors, without cords or equipment. With genuine leather between your feet and the ground, you can stay connected naturally while you walk.
These sandals are designed for a comfortable, supportive fit with adjustable straps that allow you to customize the fit across your foot.
Available in Men’s EU sizes 40-46. We recommend ordering your regular shoe size. The contoured cork footbed is shaped to support the natural curves of your foot, while the two adjustable straps help create a secure, personalized fit.

A copper rivet passes through the sandal, creating a conductive pathway between your foot and the ground. When walking on a conductive natural surface, the rivet allows direct electrical contact with the Earth.
The copper rivet sits within the footbed and most customers find the sandals very comfortable, even for longer walks. However, the rivet is a solid piece of copper, so if you have particularly sensitive feet, these sandals may not be the best choice for you. You may also notice pressure from the rivet if you step directly on a rock or other hard, uneven object, as this can temporarily push the rivet more firmly against your foot.
Grounding works best on conductive natural surfaces such as grass, soil and sand. Asphalt, wood, vinyl and many other man-made surfaces will not provide a conductive connection.
Yes. They feature a Biofresh-covered contoured cork footbed designed to follow the natural shape of your foot, along with a lightweight 8mm EVA outsole.
Yes. The adjustable buckles allow you to customize the fit across your foot for a more secure and comfortable feel.
They are designed to fit like your regular shoe size. For the most accurate fit, compare your foot measurement with the size chart on this page.
The sandals are manufactured by National Shoe in Spain. Once they arrive at our warehouse in Canada, each copper grounding rivet is manually installed by our team before the sandals are shipped to you.
No. These are designed for outdoor grounding through the copper rivet, so there are no cords, plugs or electrical outlets required.
For the most direct conductive contact, bare skin should contact the copper rivet. Conventional socks can interrupt that connection. Conductive grounding socks may provide an alternative when they maintain conductive contact with the rivet.
Absolutely. They can be worn as regular everyday sandals whether you're on a conductive surface or not.
