The TRAILFLY ULTRA G 300 MAX is a revolutionary trail shoe featuring the world’s first Graphene-enhanced foam, called G-FLY. The foam delivers 25% greater energy return and retains its optimum levels of underfoot rebound and comfort for longer, so runners feel faster and fresher over greater distances. Pioneering a new way for cushioned ultra running shoes, the TRAILFLY ULTRA G 300 MAX also features a unique underfoot ADAPTER-FLEX groove, allowing it to adapt and react to the terrain like no other. And that’s not all. GRAPHENE-GRIP rubber delivers the world’s toughest trail traction, while the supportive upper fit adapts to the natural changes of the foot when running big miles. It’s time to defy the limits of your long run in the shoe awarded INNOVATION OF THE YEAR by Trail Running magazine. “A dream for long-distance trail runners” – Runner’s World UK, who named in BEST TRAIL SHOE in their 2021 Gear Awards “Great trail tech. 92%.
