Updates to Reebok CrossFit Nano 5.0

  • The Reebok CrossFit Nano 5.0 is a trainer designed for CrossFit and other high-intensity workout sessions. It uses durable materials like the Kevlar-infused mesh upper. This material can withstand recurring friction caused by constant rope climbing activities.
  • The midsole is made of the NanoShell technology. It is designed to cup the foot to keep it steady during lateral movements.
  • The underside is protected by carbon rubber. It features the RopeTec technology at the midfoot which helps to bite the rope during rope climbs. There’s also the Metasplit innovation that facilitates natural foot bending and expansion.
  • Though the CrossFit Nano 5.0 shares the same cut as its predecessor, there are notable differences between the two. The most striking feature the CrossFit Nano 4.0 had wasa the DuraCage element at the upper. This plastic material is what protects the mesh against abrasion. In the Nano 5.0, the DuraCage was replaced by the Kevlar reinforcement for enhanced durability.


The bottom of the CrossFit Nano 5.0 from Reebok employs a carbon rubber material. This compound is durable, protecting the shoe against hard and abrasive surfaces like concrete.

The outsole utilizes two types of tread patterns: the razorblade-like nubs and the flat lugs. The serrated structure delivers grip at the forefoot while the latter helps in keeping the heel stable, especially during weight training.

Like most CrossFit shoes from Reebok, the shoe sports the RopePro technology in the midfoot area to protect its sole during rope climbs. It also features a serrated tread that bites the rope for a controlled climb and descent.

The Metasplit marking is visible in the forefoot section. It refers to the deep grooves that lie parallel to the phalanges of the foot when worn. The furrows imitate the mechanism of the phalanges, allowing for more natural movements of the foot.


The Reebok CrossFit Nano 5.0 employs the NanoShell midsole. This cushioning platform is made from a hard thermoplastic polyurethane frame that is designed to deliver support during side-to-side movements.

The midsole sports a low-profile construction that renders stability, especially during heavy weightlifting. It also has a 3-mm drop which means that the heel is not high, unlike proper weightlifting shoes.


Protecting the foot is Kevlar-infused mesh upper. This fabric is engineered to be durable to withstand abrasions associated with the CrossFit workout, like rope climbing, which could severely damage the facade of the footwear.

A traditional lace-up closure is featured at the midfoot. Six pairs of eyelets allow wearers to customize the fit. They can utilize the last two top holes for a more secure hold at the ankle, or leave them unused for more freedom of movement.

At the back, an internal heel counter is palpable. It is shaped to cup the end of the foot to keep it steady and prevent it from slipping out while training.

The thin tongue protects the instep from irritation. It is attached to the inside of the shoe via stretchy straps on both sides. The elastics help to keep the tongue in place. The footgear also employs a plush collar that enhances the comfort and fit of the upper.

Additional Info

While Reebok Nano 5.0 has gained a very positive reputation among training aficionados across the globe, it still comes short of the fit and comfort compared to the more recent Nano 8 Flexweave. Years of experience through trial and error have allowed Reebok to address many gripes and demands of the Nano fans in its newer versions.
