Stone nubuck has a soft, velvety surface and a muted grey finish.
What is grounding?
Grounding means making an electrical connection between your body and the Earth. The Brio has a pure copper plug through its leather sole, creating a conductive path when you stand or walk on a conductive ground surface.
The copper connection is one part of the design. The wide toe box, zero-drop heel, and flexible sole are what let your feet move naturally.
Shaped like feet.
This shouldn't be rare, but it is. Let your feet be feet with our wide toe box, zero-drop heel, and thin, minimal sole.
Space for your toes to spread. Flexibility to move naturally. Nothing forcing your feet into a shape they weren't made for.

Frequently Asked Questions
How should the Brio fit?
The Brio fits true to size without socks. If you are between sizes, sizing up is generally safer for a relaxed fit. Use the size finder above with your foot length for a recommendation.
Will the leather soften with wear?
Yes. Natural leather stretches and breaks in. A snug fit can relax, but do not rely on break-in to fix toes that feel jammed. Try your pair carefully indoors first.
What makes these barefoot shoes?
The Brio combines a wide toe box, a zero-drop heel, and a thin, flexible sole. That means room for your toes and freedom to move, in an everyday slip-on.
How does the copper plug work?
The copper plug passes through the sole to create a conductive connection with the ground. Grounding depends on contact with a conductive surface; the plug does not make every surface conductive. Learn more about grounding.

This is my second pair of this style in this color. I keep the older ones for more rugged activities. Altogether, I have 7 pairs in various styles and colors. I can’t go back to conventional shoes. The grounding and the exercise of foot muscles by walking “barefoot”, can’t be beal. My feet and ankles feel stronger.
I also have a pair of buffalo horn blue llight blockers and will next buy a grounding sheet.
Excellent craftsmanship, materials and customer service.

I love the look and style of these shoes and the material is so lovely and soft. They have already started to mold to my feet after just a couple days. I do wish the leather at the back of the heel was smooth instead of suede though, the suede feels a bit irritating on the heel. I’m assuming it will smooth out with wear. The only other thing is that I wish there was even more space in the toe box. Perhaps I should have sized up, maybe size up if you want extra toe width

Amazing shoes ! My husband has 2 pairs.

Love these shoes, can't recommend more

I love these. I have another pair from a competitor and these are definitely better shoes.

Great, natural material that breaks in quickly with daily use. Great to wear indoor and out in good weather.

love these... super comfortable and also higher end looking, which is great for grounding shoes! very nice leather! Got the white and they are good looking!
T
Perfect in every way. Comfortable, well made, durable and great fit. While a little pricey I found very good value. In my office alone several have ordered the same pair. They’re catching on!! Thanks for such a great pair of shoes!!
A
This shoe is very comfortable, good quality, will order another pair.

Ok so these shoes arrived a tad small and i had to order a size up. However this is the only negative thing I have to say. Clearly they are a quality product. They are stylish and can be casual or dressed up. Just holding them you can tell that they are well made to last. Will certainly be purchasing again I can tell already.
M
Happy with these so far and just had a friend notice them and was asking where I got them. Very comfortable and roomy. I have flat wide feet so the wide toe box is great. The copper plug sits right on the K-1 Yong Quan point which is the grounding point on the kidney meridian. It really is a genius design. I will purchase other styles. Size up on Brio. I wear an 8 and sized up to 9. Fits perfectly.
A
Amazing quality, super comfy and love the look. A must get! Also sizing recommendations are spot on.
K
Great shoes! They fit true to size, are very comfortable, and feel high quality. My husband wears them all day and says they provide excellent support. They look stylish, are well made, and seem very durable. Definitely a great purchase—we would buy them again!
C
Fantastic quality. Exactly what I was expecting. I can tell I'll have these for a very long time
R
This is my second pair of rhizals barefoot shoes. I love these shoes.
K
This fit perfectly, is surprisingly comfortable, and looks great. The sole is a little slippery, which might be typical of grounding shoes (this is my first pair, so I don't know). But I'm very happy with the shoes.
E
So far, amazing! Super comfortable and do seem to be well crafted. I’ve been wearing these everyday and plan to get another pair
T
They are comfortable and the size is correct but they slide a little bit pushing my toes forward. I think once they’re broken in this will go away.
P
These are great, I went from a sneaker head to wearing these full time and my feet feel great!!
G
Comfortable. Shaped like feet. Little bit snug but stretched to fit. Highly recommended.
R
Love these shoes, old and new. Had some trouble figuring out the right size, But once I did I can never go back to a regular shoe. I have a narrow foot ( okay it's bony) So I went with a women's unisex Brio because it is not as wide and it fits perfect. These being grounding shoes is a major plus, even if they weren't I would still buy them.
D
Quality leather goods! Also so comfortable!

Great fit and style - love the color!
