Kevlar® Case Study: Five Years of Innovation in Reebok Crossfit® Nano 5.0


Kevlar® and Reebok team up to develop the highly anticipated Reebok CrossFit Nano 5.0

Reebok, the leaders in CrossFit® product innovation and engineering, has marked its five year anniversary as official CrossFit footwear and apparel partner with the launch of the highly anticipated Reebok CrossFit Nano 5.0 – a training shoe that features DuPont™ Kevlar® material known for its extreme strength and durability.

Engineered specifically for the CrossFit athlete and developed in association with the CrossFit community, the Reebok CrossFit Nano 5.0 features a number of updates making it the ultimate training shoe. Reebok continues its on-going evolution in footwear for CrossFit with the introduction of DuPont™ Kevlar® material throughout the upper of the shoe for increased durability and abrasion protection.


Specifically, DuPont™ Kevlar® features in the innovative 360° BulletCage built for added protection and designed specifically to help endure the most challenging and diverse CrossFit WODs. It provides protection and durability with grip, traction, and stability while staying true to CrossFit’s mandate that the Reebok CrossFit Nano 5.0 is built on the empirical design spec of human movement.

In addition to the revolutionary addition of DuPont™ Kevlar® material, the Reebok CrossFit Nano 5.0 boasts a newly engineered anatomical heel counter and foot bed with an R55 platform for additional high rebound and cushioning. The Reebok CrossFit Nano 5.0 also offers traction working alongside a full rubber sole with MetaSplit flex groove and heightened RopePro+.


Steve Weiss, Corporate Development at CrossFit, Inc., commented: “We know how important it is for CrossFit gear to stand up to the rigors of constantly varied functional movements performed at high intensity while not interfering with performance. We work very closely with Reebok and the CrossFit community on footwear and apparel that continues to develop and evolve as the boundaries of fitness are pushed.”

“As CrossFit workouts get tougher and CrossFit athletes get stronger – so too does the Reebok CrossFit Nano,” said Corinna Werkle, Head of Training at Reebok. “With the introduction of DuPont™ Kevlar® material, we truly believe the Reebok CrossFit Nano 5.0 is our toughest shoe yet and can withstand even the harshest, toughest WODs.  At Reebok, we are hugely proud of our long-standing partnership with CrossFit; it has powered a huge range of innovative CrossFit apparel and footwear and the Reebok CrossFit Nano 5.0 is the latest landmark addition to the category.”

“The Reebok CrossFit Nano 5.0 is our most innovative and supreme CrossFit specific shoe to date,” said Dan Hobson, VP of Footwear Design at Reebok. “With the inclusion of DuPont™ Kevlar® material, which is known for its extreme strength and durability, we are sure that the Reebok CrossFit Nano 5.0 will become a firm favorite in boxes around the world. We have worked hard to design and produce a piece of footwear that puts the athlete’s needs first, and we are confident that the Reebok CrossFit Nano 5.0 is the shoe for all CrossFit athletes, from the bottom of a burpee to the top of a rope climb and everything in between”.

“The science and engineering behind DuPont™ Kevlar® enables athletes to Dare Bigger™ and push the limits of their sport,” said Kathy Kowalski, global brand and marketing communications leader, DuPont Protection Technologies. “We are very excited that through the new collection and the Nano 5.0 DuPont™ Kevlar® will play a part in the outstanding athleticism that marks the CrossFit Games.”
