    Love this shoe!

    I have two pairs of the adapt runners and have ran half marathons in them. These shoes are the only ones that don’t put strain on my feet or give me shin splints. I then decided to get the trail runner for my hikes in Banff. I did over 40 miles in a 5 day period and never had any problems with them. I went through muddy trails to rock scrambling on peaks. Not to mention I got the coconut color and they stayed pretty clean, when I did clean them everything came out with ease. These shoes work so well for me, I love them!

    Top of the rock

    Fit wonderfully, and provided a fantastic grip on the trail to the top of Moro Rock in Sequoya National Park! I loved these shoes so much I bought two more pairs.

    The best shoes I’ve ever owned!

    In my 37 years of existence and being an athlete since birth, these are the absolute best shoes I’ve ever owned. These are my second pair of Flux shoes and I’m a customer for life! As someone with wide feet I was immediately sold on the wide toe box. And the CLEATS!! They’re amazing for the trails, I’m never afraid to put it into 4 wheel drive when ascending or descending a climb. If you’re an outdoor enthusiast, stop thinking about it and buy you a pair TODAY!

    Great Golf Shoe!

    I was turned on to these shoes from this YouTube video, quite by accident.

    It was enough to get me to your site and eventually purchase these shoes in the seasonal light beige as my new golf shoes. I have a pair of conventional shoes that I have worn to death. I didn’t know how little they supported my feet until I tried these. I’ve only had a chance to use them once so far but it was the most comfortable my feet have been in a pair of shoes, let alone being on the golf course. The tread is perfect to grip the greens during my golf swing and the higher sock-like top of the shoe supports my ankles. I couldn’t be happier.

    Great Balance and Barefoot Feel

    Comfort and Fit:

    It is very comfortable. The wide toe box has greatly improved my balance and stability. The fit is true to size and provides ample space for my toes.

    Barefoot Sensation with Support:

    These shoes offer a barefoot feel with added elevation and cushioning. They provide the support I need while maintaining a natural posture.

    Design and Style:

    The design is sleek and versatile, looking good with both athletic and casual outfits. I’ve received several compliments on their style.


    These shoes are durable. After several weeks of use, they show no signs of wear and tear, and the grip is excellent.


    I highly recommend the Flux Adapt Trail Runner for its comfort, support, and barefoot sensation. They’re a great choice for both running and everyday wear.

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 toe-box 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.

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.
