Graphene crosses the finish line

Since it was first successfully isolated in 2004, graphene has revolutionised the fields of science and engineering. Now the forerunner of advanced materials is having an impact in another sector – sportswear.

Innovation = improved duration

From the Olympic track to the catwalk, trainers have an incredibly wide reach, with their popularity soaring over the last half a century. Yet, more than 100 years since the creation of the first running shoe, many still lack the durability and grip for the most demanding runs. 

Fell running, ultra-marathons and other extreme running events require a trainer that is extremely durable. These athletes want reliable footwear for both peak performance and safety. The answer –  graphene. 

G-SERIES

Graphene researchers at The University of Manchester focused on integrating graphene into rubber to enhance athletic footwear. Led by Professor of Nanomaterials Dr Aravind Vijayaraghavan at the National Graphene Institute (NGI), in partnership with sports brand INOV8, the research revealed that graphene could significantly improve the mechanical properties of rubber. 

Following this discovery, NGI scientists worked closely with INOV8 to infuse rubber with graphene and create an innovative composite. This composite was used to make the outsoles of the brand’s G-SERIES – 50% stronger, 50% more elastic and 50% harder wearing.  

The result was the world’s first graphene-infused sports shoe, known as the G-GRIP. The footwear line featured graphene-enhanced outsoles that provided superior grip and resilience, crucial for extreme sports and rough terrain. 

Overcoming limitations

The research demonstrated how graphene's unique properties can overcome traditional material limitations. The partnership also boosted the University’s commercial reputation and spurred further innovation in graphene applications.  

The G-GRIP quickly gained popularity, demonstrating the commercial viability of graphene-enhanced products and boosting the reputation of both the University and INOV8.  

Following their first collaboration in 2018, INOV8 and the University subsequently developed G-FLY – a foam midsole with embedded graphene that was launched in 2021. Tests revealed that the foam provides 25% more energy return compared to standard EVA foams and offers significantly better resistance to compressive wear. As a result, it preserves optimal bounce and comfort underfoot for extended periods. This enhancement allows runners to sustain higher speeds over longer distances, keeps their feet feeling fresh, and extends the overall lifespan of the footwear. 

The project has set a benchmark for integrating advanced materials into consumer products, showcasing the University’s commitment to commercialising cutting-edge science and facilitating a rapid transition from research to market. This success has stimulated further research into graphene’s applications to athletic equipment, with ongoing investigations into reducing product weight while maintaining high performance and exploring new manufacturing processes.
