Grounding tech that reconnects you to the Earth’s natural energy. By transferring electrons from the ground, it helps reduce stress and inflammation, improve sleep, and boost recovery.

  • Enhances Connection to the Ground: Grounding (or earthing) allows the body to absorb electrons from the earth, which may help reduce inflammation, improve circulation, and support recovery.
  • May Reduce Stress & Fatigue: Some research suggests grounding can help regulate circadian rhythms, leading to better sleep and reduced fatigue.
  • Improves Stability & Balance: A direct sensory connection to the ground enhances proprioception, helping you react faster and stay balanced in motion.

Unrestricted Steps

Move naturally, all day. A zero-drop sole and ultra-wide toe box support posture, balance, and foot strength—without restriction.

Comfort in Motion

Subtle support you’ll feel with every step. The AdaptSol™ insole features 100+ micro-massage nodes that deliver continuous comfort and sensory feedback.

Refined Grounding

Earth-Link™ reconnects you to the Earth’s energy—helping reduce stress, support recovery, and bring balance to your everyday rhythm.

Modern shoes limit your mobility. Natural movement shoes let them move as they should—building strength, improving balance, and supporting posture. With a wide toe box and zero-drop design, they help you move freely, comfortably, and naturally.

The amount of time it takes to transition to barefoot shoes varies for each individual, as everyone's feet are different and may adapt to the new shoes at different rates. However, the following general guidelines can help:

  • Gradual transition: Gradually increasing the amount of time you spend in barefoot shoes can help reduce discomfort and allow your feet to adjust to the new sensation of walking without shoes.
  • Start small: Begin by wearing barefoot shoes for a few hours at a time and gradually increase the duration as your feet get used to them.
  • Listen to your body: Pay attention to any discomfort or pain you experience while wearing barefoot shoes. If you experience discomfort, take a break and switch back to your regular shoes for a few days.
  • Give it time: It can take several weeks or even months for your feet to fully adjust to barefoot shoes, so be patient and persistent.

Keep in mind that everyone's feet are different and the transition time may vary. It's important to listen to your body and adjust accordingly to ensure a comfortable transition to barefoot shoes.

No, the leather is not vegan.

The Adapt Leather Trainer is FREE from PFCs + PFAs.

A wide toe box refers to the space at the front of a shoe, allowing the toes to align and spread naturally. This design helps reduce pressure on the toes, improving foot function and comfort. Flux shoes have a generous toe-box, thanks to the toe-off shape which creates ample room for the toes throughout the gait cycle.

Zero-drop means the heel and toe of the shoe are level, promoting a more natural foot position and stride.

Adapt Leather Trainers fit small for most. We recommend sizing up a 1/2 size for the best fit. For more details, refer to our size chart for guidance on finding your perfect fit.

Spot Cleaning: Using water, mild soap, and a soft bristled brush or microfiber cloth, focus on the particularly dirty areas (outsole or on the shoe). Do not use bleach. Do not machine wash.

We gladly accept returns and exchanges on unworn footwear for 30 days from the date of purchase (exceptions apply*). We reserve the right to refuse returns on worn merchandise. 

To ensure that shoes are not damaged, we encourage you to try the shoes on with socks on a carpeted surface when you receive them.

These and my adapt runners are my absolute favorite shoes. I see a lot of run small reviews and I did not have that problem at all. They fit perfect! I usually do my lower body lifts in these and going to buy a 2nd pair for everyday shoes!

Terrible, I bought a men's 9.5 like all my other flux and they aren't even a men's 8.5, I gave them to my 14 Y.O. son who wears a 7.5 and the y fit. Problematic QC not going to be investing in Flux shoes again.

Not a rating for the shoe because I never received the one I ordered but got a different pair. CS hasn't been too helpful, got email with a link to process a return/exchange/refund but wouldn't know because SURPRISE: Their return portal is disabled. This is my 3rd order. No problems before, this one however, big problem. Hoping CS reps see this to streamline my process. Good luck to us all.

I wanted to love these shoes, especially after the Adapt Runners didn't work. Unfortunately, the leather shoes are worse. I walked around my home to try and "adapt" but just had to remove them. I wear barefoot shoes all the time. I have never had a pair so hard and inflexible as these.

I am mostly **** because I can not get a refund as I purchased them from the clearance section. IMO, It is this very reason that people continue to buy from Amazon as oppose to directly from the company. Most return policies can not match Amazon. This would be a moot point and I wouldn't be out $108..

I sized up and my shoes were still a full size too small. In addition these shoes are very narrow, despite the natural foot look. I am past the return window, so I'm stuck with a beautiful pair of shoes that don't fit. I'm not sure sizing up would help with the narrow issue.

4th pairof Flux & I love them. They aren’t for running but walking on concrete and on my feet all day these are comfy! I’m gonna cry when I get them dirty for the first time

I absolutely love these shoes! They don’t hurt my feet at all & I don’t feel any leg or foot or back pain. I love the wider with in the toe area so I don’t feel cramped in there. I usually have to wear insoles with any of my shoes, due to being flat footed with no arch. I did not do that with these. Worked well for my job, plus walking around in Mexico!

They are comfortable and work great for standing at work. The leather has broken in nicely and I like that I can wear them with khakis, jeans, or joggers. Very versatile.

Wish I could return these but I bought them on sale. They are not as cute in person as on the website. Kinda clunky and have an odd shape. I love my adapt runners but I probably won’t wear these much. Not as comfortable either. Such a bummer.

Fit small - size up

They fit small, definitely size up! I wear a men’s 10 in the flux adapt runner and it says they fit small too but I would say those fit slightly small and these fit very small. I ended up keeping a size 11 in these leather trainers. Probably could’ve gone 10.5 but 10 was definitely too small. Super comfy soft leather though. Great shoe so far.

Comfy but durability is in question

Back again a few weeks into wearing these shoes! They’re the most comfortable sneakers I own, and the leather is very easy to clean. However, the laminate on the trim of the soles is peeling off in some areas. This doesn't affect the color much nor the functionality of the shoes. It’s purely a cosmetic error you can only see up close. That being said, given the cost and the fact I’ve only had them 3 weeks, I’m bumping my rating down from 5 to 4 stars. I do not regret buying though, still love these shoes!

I absolutely love my Flux shoes! I have a very severe and very painful bunion. Unfortunately, i also have plantar fasciitis so i have to wear insoles for arch support. My Flux shoes have such a roomy toe box so my bunion is not squeezed. They also have normal heel height so that my insoles fit well. They are the perfect shoe for me, and i’m very sincere about that. I have ordered another pair just to wear around the house. Total comfort.

Love!!!!

These sneakers are super comfortable and a very quick break in. I’m excited to see about durability over time as it’s a very soft leather, but so far they feel very high quality. They’re super cute; they’re a great incognito barefoot shoe. These sneakers work great with my casual workwear and daywear! Note, I generally wear a womens 9-9.5; in this brand I wear a womens 9.5 for my trainers and trail runners. Upon reading review recommendations, I ordered half a size up, a womens 10, and they fit great! Very pleased with this purchase so far!

Fit great, look great!

I’m a nursing student, and my uniform requires solid white shoes that are liquid impermeable and non slip. These shoes check all those boxes, look great, and are so comfortable. The only downside is the price, but when considering that one pair of clunky shoes we all wear to clinical (iykyk), it’s actually a bit more affordable. I wish these had come out sooner so I could have invested in them initially. I added some elastic laces so I can slip these on/off easily, so the ones pictured are NOT what come with the shoes.
I am also a repeat flux customer. My *normal* shoe size is about an 8, for flux I wear a 8.5 in the adapt runner, and I sized up to a 9 in these leather shoes. Just to clarify, size up one full size (at least) from your normal shoe size for these specific shoes!
If you want more guidance, I wear (women’s) size 38 in Birkenstocks, 8.5 in brooks, 8 in hokas, and 8.5 in earth runners.

Cute and comfy

So far they’re really cute and comfortable. I will say that hopefully over time they feel a little more roomy even though I ordered a half size up like recommend. I’m unsure if the stitching is meant to be kinda wobby sobby(imperfect) , but it gives the shoe some character.

This leather shoe is light and stylish, and (true to advertising) very, VERY roomy. I love wearing these and have gotten many compliments about them.
The Flux sizing formula is accurate, so please keep that in-mind when ordering. Overall I’m very happy with this product…Thank you team Flux!

Easily my favorite shoe. Best combo of comfort and style in the barefoot shoe world

M

I like the way the show feels. A flat show but ot could include more cusion on the insols. A version with arch support would be perfect. They are true to size so i would recommend a half size bigger.
