The Adapt is hands down, the only shoe I have ever felt good lifting in. The zero drop and flexible sole make me feel like I'm training barefoot while simultaneously feeling protected and able to handle higher impact training. I've never found that in a shoe before.

I have literally tried every lifting/ fitness shoe on the market. The adapt trainer is a game changer for me because of the flexibility, comfort, and the fact that they look so cool. I have ran, lifted, and jumped in them. They check all the boxes.

I especially love the adapt shoes because they allow for great stability having a flat sole and and wide toe box. Not only that, but they are also comfortable, stylish, and super easy to slip on.

The Adapt Trainer is the modern minimalist shoe I've been waiting for. Perfect foot shape fit, stylish to wear beyond the gym/workout, and the fact that they clean so easily in the wash is icing on the cake.

I've hardly worn any other shoes since getting my first pair. Adapt trainers are crazy comfortable, super flexible, and surprisingly durable. They are my go-to everyday shoes and I genuinely highly recommend them.

    Absolutely love these shoes!

    Best shoes I’ve found for my day to day activities and the gym! I have over pronated for years and relied on custom orthotics / inserts for many of my shoes. While they were fine for lifting, they were awful to wear for extended periods of time and made my imbalances more pronounced. These have helped in slowly correcting my over pronation and related issues. I can wear them for hours without the pain I used to experience. As a plus, these shoes wash better than any other trainer I’ve had.

    Hoping they continue to come out with more color variations and offer a graphene or reinforced version of this shoe for lifting (not the high-tops).

    Fit and Feel Great but...

    My all white sneaker has a lot of ivory colored parts. I just wish it was a TRUE white everywhere. Not catastrophic, but might be something that matters to others considering a purchase :)

    So happy to have been introduced to Flux!

    Needed a new trainer for my workouts (lifting, HIIT, etc.). I was wearing On's version of a trainer but I wasn't thrilled with them. I am THRILLED with Flux! I thought maybe there would be a "break in" period or time to get adjusted to the zero drop but not for me. I look forward to slipping these on for my workouts. I wear a size 9 womens and ordered my Flux in this size. If I wanted to wear socks with them I would've ordered a 1/2 size up. Since I wear them sockless, they fit great! I've been spreading the word to my workout buddies about Flux. I highly recommend them. I'm now looking into purchasing a pair of runners for my outdoor activities (biking, walks with my dog, etc.).

    My most versatile shoes ever

    I have bought two pairs so far. The first pair (black) has lasted me almost 2 years now and still going strong! That part has traveled with me through all the places, Mexico, Switzerland, France, Belgium, Netherlands, and Germany. I love the natural foot shape design (although can be a tad wider to make it perfect, will try the runner next). The upper is holding up very well, no rip, no blemishes after all the use. The sole is holding up very well too. Only getting thin at certain spots but it’s as expected when I wear them almost daily. Well done Flux! My only recommendation is to create a wider version of the trainer as an alternative, and more fun color ways. I would totally buy it again! If you plan on buying a pair, and you are sort of an in between sized, always buy the bigger size. I am a 12.5 usually, so get the 13.

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.
