"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."
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.

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.
Graphene is a one-atom-thick layer of carbon arranged in a honeycomb pattern. It’s the strongest material ever discovered—200x stronger than steel—yet incredibly thin, light, and flexible. Helping you push the limits of durability and responsiveness.
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.
Ripstop is a performance fabric woven with a special crosshatch pattern—tiny reinforcement threads that make it resistant to rips, tears, and abrasions. Even if you scuff or snag, that damage won’t spread. From rope climbs to sled pushes, CrossFit demands a lot from your shoes. Ripstop gives you durability where you need it most, without adding weight or stiffness. It’s light, breathable, and tough as hell—so you can train hard and move naturally, without your gear holding you back.
Adapt Graphene RR 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 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.
