The INOV8 Trailfly Ultra Max G 300 Mont Blanc Edition are trail running shoes for neutral runners, designed for very long distances. The design is inspired by Europe's most famous mountain. The mountain's elevation (4810m) is indicated on the midsole and footbed. The lines on the shoe are contour lines inspired by the Alpine region. The breathable upper keeps your feet cool as you rack up the miles. The Trailfly is designed for very long distances on both unpaved and paved paths. Thanks to the ample cushioning and innovative sole composition, the Trailfly performs best on paved trails and paths. Walking from the road to a trail? That's no problem either, thanks to the 4mm lugs. The Trailfly features the world's first cushioning material reinforced with graphene. Graphene is the strongest and thinnest material on earth. It is made from graphite molecules. It's so thin it's almost invisible. This thin layer is incorporated into the midsole. Graphene is 200 times stronger than steel, yet it's also very flexible. Because it's so flexible, the layer moves with your foot's movement. This strong layer protects your feet while running trails without you even noticing. By incorporating graphene into the foam, the shoes return 25% more energy than average trail shoes. This gives you a more energetic and lighter running experience, while your feet receive the best protection. Graphene is also incorporated into the outsole. The G-Grip outsole features coarse lugs that grip soft surfaces. Chances are you'll encounter paved paths or rocks during an ultra trail run. Because the outsole contains a sticky rubber, the shoes also provide optimal grip and traction. A deep groove is located under the arch of the foot in the outsole. This Adapter-Flex groove gives the shoes extra flexibility, which also means the shoes provide optimal grip during an unexpected step or situation.
