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.

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.

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.

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.

Machine Washable: Machine wash cold on a gentle cycle with like colors. If using a top-loading machine, place on top of laundry load. Let air dry, out of direct sunlight. Do not machine-dry. This will also freshen up and re-animate the interior foam. For white shoes, to preserve the color, we recommend treating the shoe with a water/stain repellent spray prior to wear. Do not use bleach.

    Adapt Runner is a winner

    These are the best shoes. I just ran a triathlon with these shoes 6 September 2025. The Buchanan Tri the Muddy Squirrel it consists of a 2 mile run,13 mile bike and 5 mile kayak. I decided to do the whole race with these shoes to save time with transitions. These shoes are so comfortable the whole way. At 62 you want a shoe that meets all demands and boy did they. I won overall master female but was 4th overall all for the women. Thank you for such a wonderful shoe.

    AMAZING

    These are genuinely the most comfortable sneakers I have ever worn. I walk 15k+ steps daily, and my feet do not hurt at all during/after wearing these. I've tried a lot of sneakers that fell apart after a few months, hurt my feet, and became uncomfortable after a few miles. I can't imagine using any other sneaker to walk in now.. If you are on the fence, buy them!!! You won't regret it. I'm going to buy my second pair to have a different color!

    Can’t go back!

    I love my Adapt runners. I’ve been wearing them to work every day since I got them. I can’t go back to my old, cramped shoes now!

    Love these

    My first pair of Flux was a pair I bought used the trail version. I was not familiar with the brand so I when on line and learned about them. I bought them I find them comfortable. So I bought two more them you runner and the water proof. I’m training for a tri. I’m 63 and love keeping in shape. I just got back from Idaho where my son took me hiking Scotchman Peak trail #65 almost a 4000 ft elevation gain in about 4 miles then back down. These shoes are great.
