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.

    Good for the office, not the gym

    I wear the black/white sole in women’s 10 with my work outfits, and they look great. I have a computer hob with walking here and there and they do just fine. I tried them in the gym, and they were a no-go for me (hence the 4 stars). The heel/ankle area was too high for me in this size. I tried a 9.5 and a 9, hoping that the slipping/rubbing would go away, but then the toe box was way too narrow. For reference I’m an Oly lifter and used these for warm-ups/accessories. I found the $40 Amazon barefoot shoes with the giant toe box in women’s 10 to allow my toes full range of motion/ground feel/stability without the heel issue. I just bought another pair of the flux trainers in white (in a 9.5) hoping to make this my everything shoe around town in 100 + degree heat. They are sooo cute with my joggers, but I won’t be able to wear these for long because of the narrow toe box issue. I’ll be returning them. Don’t know if I’ll exchange for a 10, because of the rubbing issue in ankle area, that plus sweat in the summer would probably not do well.

    Comfortable business casual shoes

    I love that these are made for athletics but I’m using them exclusively for my business casual wardrobe. The black with white sole look clean, and very flexi, and the toe box is wide, but not clown-shoe-wide. No break in time needed. And I’m enjoying the massaging insole more than I thought I would.

    The best shoes ever!

    As usual, the adapt trainer is the best shoe ever. 4th flux purchase and certainly not my last. These ones were for my son and he absolutely loves having comfortable shoes! I love that they're machine washable, so no matter how dirty he gets them, they can easily be washed between wears.

    Nice fitting

    Fit snug but needs an arch support.

    Love, love love!

    I absolutely love these shoes. I'm ordering another pair, and a pair for my husband too. I am finding that I pretty much never want to wear anything else!

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.
