Product Details
Description
These women's sandals are made in Spain and are incredibly comfortable and stylish. They feature a synthetic upper and a biofresh-covered, contoured cork footbed for exceptional orthopedic comfort and support.
The sandal upper features a double adjustable strap with an 8mm soft EVA outsole for the perfect fit. We have modified this beloved sandal into an Earthing shoe by inserting a copper rivet into the sole so you can enjoy the health benefits of grounding. Copper is conductive and allows electrons to flow through your skin. Now you can enjoy Earthing with every step you take in spring and summer. These women's sandals are perfect for Earthing, and they may help reduce discomfort from plantar fasciitis, bunions, diabetic foot problems, and other foot pain. They come in ladies' EURO sizes 36 - 41. These women's sandals are made in Spain, and we insert the copper rivet in Canada.
Benefits
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.
Sizing & Fit
These sandals are designed for a comfortable, supportive fit with adjustable straps that allow you to customize the fit across your foot.
Available in Women’s EU sizes 36-41. 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. If you are between sizes, use our size chart and compare your foot length to find the best fit.

FAQ's
How do these earthing sandals work?
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.
Can you feel the copper rivet under your foot?
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.
What surfaces can I ground on?
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.
Are these sandals comfortable for everyday wear?
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.
Are the straps adjustable?
Yes. The adjustable buckles allow you to customize the fit across your foot for a more secure and comfortable feel.
How do the sandals fit?
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.
Where are they made?
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.
Do I need a grounding cord or outlet?
No. These are designed for outdoor grounding through the copper rivet, so there are no cords, plugs or electrical outlets required.
Can I wear socks with them and still be grounded?
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.
Can I wear them even when I'm not grounding?
Absolutely. They can be worn as regular everyday sandals whether you're on a conductive surface or not.

Absolutely love these sandals!!!! They are versatile as well as comfortable for any occasion.
Love my new sandals! I usually never go barefoot anymore or wear shoes without socks but these are my go to shoes this summer! I love them and they fit perfectly.
I'm so impressed with my grounding sandals! They are my go-to shoes and I love everything about them! They won't be my only shoes from The Brown Bear for long!
Perfect Grounding Sandal!! I am completely satisfied with these sandals! I was nervous they would be too small but they fit just right! I am usually a 9-9.5 so I got a 40 and they fit so perfectly. These are my first pair of grounding sandals and I am very glad that I can wear them with pretty much anything and be connected to the earth in style!!
Love them It took me a few days because I wasn’t so sure about the copper insert and how it felt. But once I started walking in them and breaking them in it no longer bothered me at all. I love them!!!
Amazing shoes! These are my favorite shoes. They are so comfortable and I love the fact that I am now always grounded :) I am telling everyone about them. Thank you for making such great products!
Comfy and fit perfectly! I went with the brown option and found that they fit true to size. They are super comfy and cute to wear.
Beautiful Comfort I really enjoy these shoes because they are both beautiful and comfortable. I can wear them both casual and dressy. The bonus I enjoy is they are good for you health
All the way to New Zealand!!!! Hi guys, I bought 3 different pairs off here. Was a little worried about my first big international purchase, coming from Canada to New Zealand, but, no problems! All good and legit. Shoes are lovely, comfortable, grounded, adjustable, lovely fit, lovely style, no regrets. I got a 39 and a 40, because I was a little unsure of sizing. 39 fits perfectly, but 40 is also fine. !!. Got a tan and a black, and they are both nice. I really believe you will enjoy these shoes, and nice to know they're grounding you. ( been trying the barefoot thing, but its middle of June so middle of winter and cold here in NZ. So sometimes I need something on my tootsies!!!) Haven't quite reached Afghanistan Foot Solider status yet!!. Cheers, hope this helps you all! Hahahah, even my 13 yr old style guru was like, "wow, nice shoes, they look like Birkenstocks!!"
Amazing! I don't really like to leave reviews, but these sandals need one! They are so cute, they fit amazingly, the are soooo comfortable. I have always been a Crocs fan because of their comfort. Not anymore! I will definitely get myself another pair of these when these wear out. I also love how I'll be grounded.
grounding sandals I love these. They fit well, very comfortable and I just feel better knowing I have them on when I go for walks in the woods, I wouldn't go barefoot so this is the perfect alternative. They are also well priced.
