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.

    Best shoes ever!

    My niece had the most unique shoes when I visited her in Calif in March. She advised the Flux brand, and how now her shins and knee no longer hurt. Since I have a knee that ached constantly, I immediately ordered a pair. When they arrived at my Texas home, and I put them on, my steps/walk was altered due to the interior make of the shoes. It is now 1 month later, and my knee ache/discomfort is gone. I can even lift the knee to step up steps. I can’t wait to get another pair!

    Best shoes I’ve ever had!

    My feet were hurting so bad for my Brookes and I took the chance and I’m so glad I did! Not only are they are comfortable they are so cute and breathable! I got the adapt runner and sized down a half size after reading reviews. I am a size 6.5 and got a size 6 they are perfect! I’m ready to throw away all of my work shoes and replace them with multiple pairs of these! Comfy and cute!? Get them!!!

    Great shoes for working in hospital on your feet all day

    These shoes are great! Didn’t realize that this is what I needed. I suffer w/ plantar fasciitis and honestly these helped me a lot.

    I switched from hokas, to on clouds, to brooks, and now these. I like the wide toe box as well. I got true to size, but my colleague told me she wished she went up half a size.
