DETAILS
Of all the ancient inspired footwear designs we have tested over the years, no enclosed design has tested higher in overall foot health, freedom and functionality than the ancient tabi shoe design. Given its remarkable reputation, no other shoe seemed more worthy of taking our next step in earthing evolution than the top selling Sports Jog 2 from Marugo, a Japanese tabi footwear company.
Our ion Sync® Sports Jog Tabi takes an ancient split-toe tabi shoe design and combines it with cutting edge conductive polymer earthing technology resulting in a foot-friendly minimalist shoe to facilitate foot strengthening, reduce foot pain, and keep you grounded.
Features:
iON SYNC® is Patented Technology
Specs
Tabi (or Jikatabi) are traditional Japanese footwear which feature a split between the big toe and the rest of the toes to promote flexibility and provide extra security, comfort, and stability.
Together with Marugo our Ion Sync® Sports Jog Tabi take this traditional minimalist footwear design and combine it with Ion Sync Earthing plugs to offer a shoes experience that is the next best thing to barefoot.
Our grounded Ion Sync® Sports Jog Tabi Shoes feature 4 conductive rivets per shoe installed in house by our Earth Runners team. Our Ion Sync 1.0 plugs have a conductivity of <100,000 ohms which allows 60hz EMF induced body voltage to drop by 90-97% as compared to standing on the earth (99% body voltage drop).

Warranty
Our 1 year manufacturer's warranty covers failure of the outsole. This includes functional delamination of the sole or Ion Sync® earthing plugs. To submit a warranty claim, email your receipt and photos of the damage to our customer service team to assess the best means of resolution (repair, gift certificate or replacement).
FAQ
Are the Ion Sync® earthing plugs watertight?
Yes, all the earthing plugs are compression fit into the outsole making for a solid rubber seal. Also keep in mind the tabi shoes feature fabric between the toes which is the most likely area for moisture infiltration.
Can you feel the Ion Sync® earthing plugs underfoot?
If you feel for the Ion Sync® plugs you can feel them underfoot but after wearing the shoes for a while they go unnoticed.
Do iON SYNC® earthing plug contain latex?
No, our iON SYNC® earthing plugs are latex-free.
Will the Ion Sync® earthing plugs wear out?
The Ion Sync® earthing plugs are recessed and sit flush with the outsole tread at the midfoot so they are well protected. Their resilient rubber composition combined with their strategic positioning exposes them to low wear for max longevity. If they do happen to wear out, they can easily be replaced.
How do I determine how my (short/long) toes will fit into the tabi toe pocket?
We recommend everybody to print out the sizing templates in actual size to compare with your foot to confirm the best fit for your unique foot/toe profile.

I luv these Tabi joggers, I wear them around town and most of the time they are discrete. A Sneaker vibe with that Tabi comfort. I actually bought the wrong size thinking my regular size would work but found out I needed a smaller size. (28 vs 26) the customer service was super fast for an exchange and they were so professional. Getting the alpha sandals next.
i love the shoes, they are mad comfortable. i genuinely feel the grounding and it’s superb. i already had toe socks so i used them with these shoes and it works great. i love that they’re black so they go with everything. the tabis keep my feet relatively warm for being minimalist, which i am grateful for because i bought them during the cold weather season. my only critique is that i wish they had a loop in the back of the top part of the heel to help with putting them on
Love these shoes! I have some ankle instability from sitting too much and I use these shoes to get better at stabilizing my ankles myself. Used correctly, I can walk/shuffle for >5 hrs and my feet feel great the next day. I also have some other New Balance shoes with a lot of stability support that I use when my ankles are tired. The New Balance shoes make my feet painful and require a foot massage if I use them for a prolonged period of time. Working up to only needing the iON Sync shoes all the time. I also bought the toe expanders and I like these better than all the other toe spreading tools out there. I also use them with my iON sync shoes. Earth Runner sources the best stuff. Appreciate it.
Just bought my second pair of sandals as I really like wearing them. I now have one pair for trail walking/running and my second pair for casual. The Tabi shoes I bought are also great. Really comfortable. Would love to see them offered in different colours 😃
As much as I was a barefoot enthusiast all my life until my mid 20's since getting disabled by multiple sclerosis in 2011, my feet have gotten insanely sensitive and my arches got very weak. I've tried all forms of "barefoot shoes"but these Ion Sync tabi are the first that I've been able to use that helping me stay grounded, have a good grip, and no arch support to speak of so my feet are getting stronger. It's the best I've experienced in almost a decade and a half
