These have become my go-to training and lifestyle shoes. They're extremely flexible, easy to get on, and the massaging nodes inside are super comfortable. Not to mention, easy to clean and durable!

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.

    I like these a lot, just wish they were more durable for the price....

    I find these shoes to be very comfortable and wear them pretty often. However, I noticed after about two months that the fabric on the heel started to wear away. It was barely visible at first but has only gotten worse. I feel like the fabric should be a little more durable for $129.

    Big fan of the Adapt Runners, but Flux missed with these...

    I love my Flux Adapt Runners, but I wanted something that would work for the office or a casual night out. I've worn these 10+ hours a day for about 2 weeks and wanted to provide my thoughts.

    Pros:

    - They look good compared to 90% of zero drop/barefoot alternatives. I've already gotten a few compliments

    - Lightweight and breathable

    Cons:

    - The insole is not comfortable (and is sewn in so it's not removeable). The nodes are too hard and too pronounced. The best way I can describe the sensation is the numb feeling you get on the bottoms of your feet after walking on rough concrete/asphalt. I thought it would soften up, but no change.

    - Toe box is not that wide. While these are definitely wider than your vans, they don't have nearly as much room as other barefoot alternatives

    - Material feels and looks cheap up close. The body of the shoe is made out of a stretchy material that is too stretchy in my opinion. The shoe feels comfortable (ignoring the insole), but not fully secure. I'm not sure I would want to weightlift or exercise in these just because of how much your foot can move with the material. If you try to tighten them up with the laces, the material folds on itself at the toe box which you can see in the picture attached (not a great look). The tongue wants to move around a lot, and I can easily see these edges fraying.

    - Sizing is tricky. I wear an 8.5 in my Flux Adapt Runners. I saw the note saying these run small, so I order a size 9 which was still…

    A Hard Lesson

    I took the shoes for a walk one time to see if I like them or not. Decided on the not and wanted to return but was denied because they’re not “like new”. This shoe did not meet my wide toe box needs but was otherwise fine. If you want to roll the dice on these, go one full size up and just walk around the house to see if they’re for you or not. They make you take photos of the shoe and decide if they’ll return or not. Return fee is $13. I wear size 12 and purchased 12.5 and was still not enough.

    THE BEST ALL AROUND SHOE

    I have 3 pairs of adapt trainers. I wear them daily for Everything! I feel a constant massage on my feet, they are soooo comfortable! I’ve had 2 foot surgeries and I’m very picky about shoes. The toe box is perfectly roomy. I AM OBSESSED!

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.
