"I get nervous ordering online with anything I wear… The Flux Adapt Runner delivered… feels natural to foot and perfect comfort. Size is true to fit. Wide toe box is perfect and the construction is on par with a popular Swiss shoe." - Max H."

Verified Buyer

I have never been a fan of shoes. No matter the brand, I end up with sore toes, sore midfoot, or blisters… or sometimes a mixture. I was skeptical of Flux shoes, but the minute I first put them on I could tell they were completely different. My toes no longer hurt… My arch and midfoot are comfortable. No blisters! The back is so sturdy, yet so flexible and easy to get on and off. Not sure how they do it. I walk/jog at least 5 miles per day and have a standing desk for work that I am now able to stand at almost all day. My feet never hurt." - Brittany S.

Discovery why the Adapt Runner had to exist →

While yes you will receive a shoe box with a pair of shoes these shoes will be walking equipment that feature:

  • Zero Drop - Strengthens your feet with every step
  • Unmatch Comfort - Massaging your feet with 100+ AdaptSol cushions
  • Wide Toe Box - allow your toes to flex and move like they’re supposed too

The Flux Adapt Runner is designed to help you be 1% better every day. Take 2 minutes to see how

Comfort + Sensory Feedback = Improved Foot Strength

Our vision for a more freeing shoe didn’t exist. But we wouldn’t have gone down this path if we were afraid of being underdogs. After years of prototyping and development we discovered that a shoe our feet deserved wasn’t going to be cheap but to our surprise, at $139.99, it turned out to be less than some bigger brands.

No more over-engineering. Just research-backed design that moves with your feet, not against them.

A Different Approach to a Running Shoe


Natural Movement

Barefoot shoes with zero-drop, a wide toe box, and just the right amount of stretch will allow your feet to revel in newfound freedom.

Unmatched Comfort

The AdaptSol™ insole includes over 100 nodes that massage your feet and provide comfort with every step.

Flexible Traction

Lightweight and cushioned. The rubber AdaptTread™ outsole provides the ultimate traction for any adventure.

Wearing bulky shoes is like keeping your feet in casts. Sure, they’re temporarily safe, and may even be able to recover from overuse, but this is merely a band-aid, not a long term solution. Your body works and feels best when it’s being used and appropriately challenged.

  • Stronger Feet: Traditional shoes restrict movement and weaken foot muscles over time. Barefoot shoes promote natural movement, strengthening muscles in the feet, ankles, and lower legs for better stability and strength.
  • Happier Toes: A wide toe-box gives your toes freedom to wiggle and flex. This builds up their strength and flexibility, making it easier to move around without hurting your ankles or knees.
  • Balanced Stride: A zero-drop design, meaning your heel and forefoot are on the same level, gives you a natural, graceful stride that takes the strain off your joints and perks up your posture.

"Barefoot shoes" is a general term for shoes that optimize the natural biomechanics of the human foot. To achieve that, our shoes feature excellent flexibility, zero-drop (no heel raise), and a generous toebox to accomodate the foot's natural shape.

Flux shoes have a generous toe-box, thanks to the toe-off shape which creates ample room for the toes throughout the gait cycle.

Yes, these shoes are flat from heel to toe, allowing your feet to land naturally.

Adapt Runners 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.

    Two weeks and my plantar fascia is happier!

    I’ve been fighting with plantar fasciitis for a few months, because I went in the wrong direction! I had opted for a shoe with a lot of drop, and too much stack, and boy did my heel let me know!

    After the first week in my zero drop Flux Adapt Runners, my heel is almost back to 100%! Two weeks now, and I’m ready for another pair to alternate each day.

    Thanks Flux Footwear!

    Absolutely lovely

    As a physical therapist, I’m always looking for a good neutral shoe that allows for natural strength of our feet to be used, without sacrificing comfort. I’m a huge fan of Altra’s but wanted a lower price point and there was a great sale going so I grabbed a pair. The upper is so stretchy and comfortable, so I have no pressure on my little 5th toe bunionette. It allows great forefoot spread and midfoot mobility while also giving light hind foot stability. I’m definitely a fan and will be trying out other options from Flux in the future. One thing is I wish I got size 8.5 not 8, but I am between sizes. P.S. 3 of the 6 PTs I work with now have pairs of Flux’s and are all happy with them.

    My First Wide Toe Box Shoe

    This is my first wide toe base shoe and I am very pleased at the comfort and quality of this shoe. I read multiple reviews about this type of shoe and the benefits and I finally decided to take the plunge and so far I have no regrets. They are extremely easy to put on as well. I have tried wearing these with and without socks and while I am a devoted sock-wearer, after reading that it’s not necessary to wear socks I gave it a try and haven’t worn socks with these shoes ever since! I originally bought these on sale and that helped while making my decision but I plan on trying out the more casual Flux tennis shoes next.

    Great Sneakers!

    I love the Adapt Runners! I did a lot of research and read a lot of reviews before I purchased them, and I’m so glad I did. They are worth every penny. They are so comfortable and the natural toe box is the best I’ve ever worn. Great for my long runs too! I did go half a size up because that was the consensus on the reviews. They are perfect! I want a pair in every color now! 🥰🏃‍♀️

    Love Barefoot

    I am on my first day in my new Flux Barefoot sneakers and so far I am feeling pretty confident they will work. My only issue is the heel is a little shallow to start and is causing the heel to rub on the backs of my ankles uncomfortably. Otherwise, love the color and if they hold up on concrete everyday, I’ll definitely be buying another pair.
