Discovery why the Adapt Runner had to exist →
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.

    Quite Happy

    I have been wearing barefoot shoes for about 3 months. I walk 3 miles 5 to 6 days a week. I decided I wanted something with a little bit of a sole to it. I have actually been looking at these for probably a year. I am pleasantly surprised at how much I like them. I have a wide ball of my foot and have since birth, I have a high arch/instep and sensory issues on my feet. Yet I still find them comfortable. I do normally wear a size 8.5 and had to return them for a size 9. I did see reviews where the heel or top of ankle rubbed and that was a worry. I would say if that’s happening you need to size up a half size!

    The only negative for me is the insole. As you can see I end up with imprints at the end of my walks. The last half mile it’s all I notice. If anyone has any input on smooth insoles that fit these shoes well I would love to know! I wish it was an accessory I could buy! Not everyone finds it massaging.

    My foot is 3 ¾” wide at the ball and 9 ½ “ long.

    Stuck w the wrong sizes…

    Bought the Adapt Trainers about two months ago in a size 11.5 and they are too tight. Love the shoe though, I still wear them. So then I wanted to buy the runners - and trying to avoid the same mistake, I read the reviews and they said to size up. So I did, now I am stuck with the wrong shoe size ‘cuz these truly run ‘true to size’… Nothing against the shoe… Just buying the sale might be like a Russian Roulette since you can’t exchange the sizes or return the shoe… sad policies. Anyhow, love the company and the potential they have to become an industry game changer. Hope one day I get the right size with them, haha

    Love them! New favorite!

    When I first put these shoes on I immediately fell in love. They are so comfortable. At first the shoes were a little snug but as I have worn them, I have broken them in and they fit great. I went ahead and ordered another pair!

    Better than Hokas & ONs

    Comfiest shoe I’ve worn in a long time, I work in a healthcare clinic. I have worn Hoka carbon x 3 shoes for a year, they worked but not the best. I have a pair of ONs that I never wear due to the comfort being terrible, they squeak when I walk, etc. these shoes fit so nicely and let my feet breath. Can’t wait to get another pair! I also love that they don’t have huge logos on them. Size up!!!!
