Frequently Asked Questions
How should the Tanu fit?
Runs true to size. Order your normal size.
What is the natural rubber sole made from?
The natural crepe rubber sole is made from rubber-tree latex. Its flexible feel lets the sole bend with your foot, while its grippy surface helps with everyday traction. The insole is vegetable-tanned leather.
How does the copper grounding plug work?
The copper plug runs through the sole, providing a conductive path between your foot and a conductive surface such as soil or grass. Contact with the ground matters; insulating surfaces interrupt that path.
How do I care for my pair?
Brush away dry dirt gently and let the pair air dry away from direct heat. Avoid soaking or machine washing. Use care products suited to suede; smooth-leather conditioners can change the look of suede or nubuck.
Keep the natural rubber outsole away from solvents and excessive heat.

Love these shoes. Probably my favourite pair of rhizals I have. Very comfortable once broken in a bit. Great if you have wide feet as well.
A
Comfortable and stylish
J
They are very well made! I like the materials, the wide toe box, and the flat simple sole.
A few issues that aren’t deal breakers and I believe will improve with time would be my foot struggles to stay in the sandal with the flat slippery sole. I think the grounding is odd and can be uncomfortable at times, but I get the idea! Great show, I believe my foot will stay in better they break in!
J
Love them. I will buy again!

When I first got the shoes, I thought they looked way too wide and were too hard. I adjusted the straps and I gave them a chance. I slowly broke them in over a couple days just around the house. They have nicely softened up and I now love them. I’m so glad I did not return them. They just needed a little time to soften and loosen up.

BEYOND IN LOVE. I have been on the hunt for a pair of Birkenstock type sandals WITHOUT that atrocious arch. I have flat feet and am very much a fan of barefoot style shoes because they make my feet feel free. Love the adjustable straps, the leather is amazing quality, and the copper plug keeps me grounded all day long. 10/10 recommend!!!

I really love this Sandal but it is entirely too wide for my AA foot
L
Way to wide for my AA narrow feet. We do have different width feet you know…however, because I was able to adjust the buckle they stay on my feet.. updated. I really tried to make this sandal work but it is entirely too wide for my foot.

These are great like everything else in this company. I love the natural rubber on the bottom. The only reason I don’t get five stars is that it doesn’t look quite as classy to me as other offerings from this company. But I needed a new pair of sandals and I’m glad to get such a high-quality pair with natural materials.

TLDR; wore them for 20 minutes and got blisters on my feet that still haven’t gone away.
I was really excited to get these as my Birkenstocks were old and started to tear apart. I’m a big fan of grounding and was pumped when I got the ad for these shoes.
When they came in the mail I put them on to break in and went on a short 20 minute walk.
My feet were in pain and I still have fat blisters on both my pinky toes. I’m no rookie to barefoot shoes, I own plenty of Vivo Barefoot and Xero shoes that I wear all the time. I’ve worn my Havianna flip flops in Rio while walking 30k steps in a day in one of the hilliest urban terrains in the world and my feet were in better condition then compared to 20 minutes wearing these shoes.
J
They’re amazing! I love the style and comfort.
