Earlier this week, British brand inov-8 unveiled its new graphene-enhanced G-Series sports shoes to a small group of journalists. We went to England for this review.
Having learned about the impressive properties of graphene, I salivated over the world’s first graphene-infused running shoes. So I was stoked to take the Terraultra G 260 and Mudclaw G 260 for a spin on the morning following the launch.
To test the bright, lime-green fell and trail running shoes, inov-8 chose Rivington Pike. This hill sits in the West Pennines about 20 minutes outside of Manchester, England. It’s home to the oldest established fell running race in the U.K.
Rivington Pike’s mix of fast dry trail and steeper technical, soft terrain was the perfect place to put these shoes through their paces
