    My thoughts on the Reebok CrossFit Nano 8 Flexweave

    When it comes to crossfit shoes, the main model most people recognize is Reebok’s Nano series. Nano was initially introduced in 2011 after the company launched a partnership with Crossfit Inc.

    Fast forward 7 years, Nano 8 Flexweave was introduced in January 2018. Reebok definitely takes this business seriously and makes gradual improvements over time.



    One of the changes Reebok applied in this model is the inner sole the shoe has. This part of the shoe is separate from its outsole and allows users to wear the shoe even on barefoot. It provides flexibility during the training.

    For a strength training shoe, one of the first attribute consumers are looking for is durability. In general, durability means tougher outsole materials causing less flexible shoes. However, when I train with them at very challenging paces, I can feel that the shoe is a continuation of my body, providing enough flexibility I demand.

    Flexweave outsole provides enough breathability without sacrificing durability. I may not be a fan of rope climbing but in order to test it, I did a few and the shoe doesn’t show any wear and tear from this exercise. I believe the cross-weave design is providing this extra durability and pretty sure that it will last long enough before you would like to change to a more current model.


    User experience

    One common point of Nano 8 Flexweave with Nano 7 is the plastic heel cup. This is an important feature for me since as a runner, I do leg focused training and I'm not comfortable changing shoes mid-training when it includes metcon and weights.

    I did a fair amount of squats (back, front and overhead) and I can easily say that I feel the support from the plastic cup. Yet of course, it is not a weightlifting shoe so the support would be limited (especially without elevated heel) but I didn’t feel any insecurity.



    As I indicated, since my training is more focused on legs, I am benefiting from the wide toe box that the Nano 8 Flexweave offers.

    The main reason is that as an overpronator, I always feel comfortable and has more grip when I spread my toes as much as possible. With a wide toe box, this is possible.



    If you are looking for an all-around shoe which you can use during different types of exercise, Nano 8 Flexweave is the choice you should make.

    The shoe provides enough stability and support for weight training and as a result of its flexibility during plyometric training, it won't slow you down.

    I’ll put my name on line to vouch for the performance of the 8.0 as being one of the best training shoes you’ve ever tried.

    If you're looking for something that is a bit easier to run in, a little bit easier to live in day to day, but still very stable, check out the Nano 8.

    I liked the changes Reebok made to this model compared to the 7 (which wasn’t my favorite whatsoever), and the newly constructed bootie. It’s a shoe I can both workout in and wear in my day-to-day with comfort.

Updates to Reebok CrossFit Nano 8 Flexweave

  • The Nano 8 Flexweave is an update to Reebok's prominent line of CrossFit shoes. The most distinct difference between the Nano 8 Flexweave and the original Nano 8 model lies in the construction of the upper. Though they both feature the Flexweave material, the newer version has been re-engineered for enhanced breathability, support, and durability. It sports a Figure-8 construction that ventilates and reinforces targeted areas.
  • It comes equipped with an inner heel bootie sleeve for additional comfort. It also gives a sock-like feeling that makes the shoe fit more snugly.
  • The forefoot area is designed to be more protected and cozy due to the added cushioning. This feature makes plyometric exercises safer and more pleasant.
  • It utilizes the Toe Tection technology in the toe area. It makes the upper resistant to the wear-and-tear during high-intensity workouts.
  • The outsole has been designed to meet the specific requirements of CrossFit. It offers a strong grip on indoor surfaces.

Reebok CrossFit Nano 8 Flexweave size and fit

The Reebok CrossFit Nano 8 Flexweave was released for both male and female athletes. The men’s version comes in US sizes 7 to 13 and in a D - Medium width profile. For the women’s model, it is available in US sizes 5 to 10 and in a B - Medium profile. The heel sleeve delivers a snug fit at the rearfoot while the lacing structure allows users to customize the looseness or tightness of the midfoot. The boxy forefoot also accommodates various foot dimensions and permits unhindered toe splaying.


The bottom of the Reebok CrossFit Nano 8 Flexweave is made from high-abrasion rubber. This compound is engineered specifically to deliver traction during dynamic routines involved in CrossFit and other high-intensity workouts.

At the forefoot, the “Metasplit” marking is clearly visible. It pertains to the deep grooves that mimic the phalanges of the foot, allowing the outsole to bend and move naturally with the foot.

The RopePro technology is seen at the lateral and medial sides of the midfoot. It has ridges that aim to bite the rope during rope climbs and descents for controlled motions.


The Reebok CrossFit Nano 8 Flexweave uses a dual-density midsole to fulfill the various demands of CrossFit. The heel area is created to be rigid to give support during lifts. On the other hand, the forefoot is more flexible and cushioned to cope with high-intensity fitness routines and plyometrics.

It has a minimal drop of 4 mm to grant secure footing to the athlete. It leads to a more stable platform during heavy lifts.

Inside the trainer is the OrthoLite sockliner. This component not only enhances comfort but also helps in attenuating shock that travels to the foot and the rest of the lower extremities.


The Reebok CrossFit Nano 8 Flexweave features a low-cut design to encourage full ankle mobility. It lets the wearer move unencumbered during workouts.

The footgear has two layers of upper. The outer part is made up of the Flexweave technology. It comprises an innovative Figure-8 weave that interlocks each fiber for a durable, supportive, and flexible support. The knit is also designed to be breathable to allow air to circulate inside the shoe.

Meanwhile, a heel bootie sleeve gives the foot a pleasant sock-like experience. It offers comfort and a snug fit at the ankle area.

A traditional lacing system adorns the midfoot. It allows users to customize the tightness of the fit for their desired locked-down experience. The instep is protected against irritation by the lightly padded tongue.

An overlay reinforces the eyestay so the holes won’t easily get ripped when the laces are cinched. This element continues around the collar, protecting high-wear areas against abrasion.

The Toe Tection technology is installed on the upper to boost durability. It reinforces the toe box to prevent ripping and protect the toes against bumps during specific workout movements.

At the back, a thermoplastic polyurethane (TPU) heel clip can be found. This structure is rigid, cupping the rearfoot to keep it steady and prevent slippage.
