    Let’s just put it this way, if you were to send me to the CrossFit Games with only one pair of shoes and absolutely no knowledge about what the workouts are going to be, my choice would be the Nano 9’s.

At first glance, it is hard to believe that these two trainers come from the same series of Reebok CrossFit footwear. Even if you put them side-by-side for a more in-depth comparison, you will only find a few similar-looking features. However, at their core, these two Nano models have been crafted with the same principle in mind: to serve a comfortable, do-it-all CrossFit trainer that would bridge the gap between weightlifting and running.

A considerable number of users have already agreed that the Nano 9 feels as if it does everything that the Nano 8 does, but better. So, what are the key ingredients that help the latest edition step up the game?  

- Enhanced stability. One of the most apparent alterations in the Nano 9 is the translucent rubber wrap found on both sides of the midsole. It replaces the NanoShell heel clip of the previous Nanos. The new wrap has been widened out and extended closer to the midfoot. That way, it covers a larger area, helping the foot feel more steady during weightlifting and multi-directional movements. By checking the back of the shoe, you can also discover that the heel section has been broadened significantly. The edges of the sole have been made more clear-cut and less rounded, making the shoe’s platform resemble that of a weightlifting shoe. All of this has been made for the sake of stability.

- More running-friendly design. Despite the reinforced stability department, Reebok has also found a way to improve the trainer’s performance for running. It has added more cushioning into the midsole portion by using a single-density injection-molded EVA foam. To put it simply, this type of foam has a lighter and more flexible characteristic and offers more rebound than the harder foam used on most cross-trainers. While it doesn’t turn the Nano 9 into a dedicated running shoe, it makes the trainer more responsive for short runs (1 to 3 miles) and jumping exercises. At the same time, the afore-mentioned rubber side panels do not let to compromise stability. Unlike the old NanoShell, the new wrap is decoupled at the back, meaning that it consists of two pieces which are not connected at the rearfoot. This design twist also aids in making the heel-to-toe transition much smoother.

- Improved foot containment. The already acclaimed Flexweave material receives a new life in the Reebok Nano 9. It has undergone a transformation which gave it a more stretchy quality. The fabric itself has been made thinner and tighter to conform to the foot shape more seamlessly.

- The heritage logo is back. The brand brings back the classic Vector logo onto the lateral side of the trainer. According to Reebok’s Senior Product Manager, the new design makes the shoe appear slimmer and faster. It is also meant to give the trainer a more sneaker-like vibe. 


The ninth iteration of the brand’s flagship CrossFit shoe came out under the “Designed for all” slogan as well as the “NanoForAll” hashtag. These mottos represent Reebok’s endeavor to create a shoe for every level of CrossFit engagement: from newcomers to the Fittest Men and Women on the planet. Thus, the brand has worked closely with the CrossFit community to get all the feedback first hand. This is how years of experiments and testing have helped the company shape its “best Nano yet.”

Traction. Both types of rubber that are found on the outsole are meant to grip the gym floor efficiently. To enhance this asset, the shoe employs a diamond-shaped tread pattern which is also reminiscent of the barbell knurling. It is designed to bite into the surface and help the wearer stay glued to the floor or stop short during dynamic movements.

Protection. One of the rubber compounds extends up on the front and medial sides of the shoe. At the front part, it forms a shield for the toes which protects the wearer against painful toe bumps. On the medial side, the rubber bears the RopePro add-on. It assists the athlete during rope climbing exercises. It grips the rope on the ascent and prevents the sole from burning out on the descent. 

Low drop. To help the wearer feel more connected to the training surface, the shoe uses a low-profile sole unit. The 4-mm heel-to-toe drop places the foot nearly flat on top of the midsole. This differential is typical of CrossFit footwear as it provides a better sense of control for the constantly varied exercises.
