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.

    Torturous to the ball of the foot, but fixable with an insole insert.

    First let me say that I do enjoy these shoes, I wear them casually and I take them to the gym on all but my leg days. They are comfortable at the gym and for daily use. But issues arise when you walk longer distances in them. I usually do two 30-minute walks every day to get my 10k steps but the first time I got the Adapt trainers I wanted to test them so I decided to do a full hour at pretty high pace. Ive worn barefoot shoes for years and spend a good amount of time barefoot so I actually have pretty thick skin on my feet. But by the time I returned from that walk the balls of my feet were on fire, they bumpy blue sole of the adapt trainer was rough enough that it rubbed thru my sock and rubbed the bottom of my foot raw. The next day I got a blister and I was basically unable to walk or workout for a week while that healed up.

    This was highly disappointing, but not as disappointing as when I contacted Flux about it. They told me these shoes are for training and not walking, despite the description explicitly stating they indeed ARE for walking. They told me to walk I need shoes that are for running 🙄. I ended up cutting up some insoles for these, and now I can walk in them with no problems. For shoes that are this expensive, you'd think they would come with some sort of insole or at least have the blue bumpy portion of the inside of the shoe lined with some sort of material to not cause massive blisters.

    Love these! But double check your size before ordering

    Love these shoes! Like a constant foot massage all day, my toes have enough room and they look great. According to the size guide I’m 24.4cm so I’m between an 8 and 8.5. It said go up 2 sizes in a lot of reviews. So I went up to a 9 and they fit amazingly well!

    I would just say, go look at the size guide and also measure your foot! Then go up 2 sizes (ex. go from 8 to 9) don’t assume your shoe size from another company will be the same for this company.

    Click on the Size guide to know they run small

    I own the adapt runner in my usual size and they fit perfectly - one of the best sneaker's I've ever had. I ordered the adapt trainer because they were on sale in my desired color. Very disappointed to find out they didn't fit, and have to go through the hassle of an exchange. Also, I now have to settle for a different color because same color in the size up (M14) is not available. "This shoe runs - small, size up" should be readily available to the consumer in the product heading and not hidden in the size guide. One shouldn't need to go looking to have to know this when ordering - bad for repeat business when there is so much variability in size for different products. Otherwise, great shoe, and looking forward to the exchange.

    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.

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.
