All about this product



The TrailFly Ultra G 300 Max is a revolutionary trail shoe featuring the world’s first Graphene-enhanced foam, called G-FLY. This cushioned foam is more resistant to wear. It retains its thickness and optimum levels of snappy energy return for longer, helping runners feel faster and fresher over greater distances. Incredible energy return and increased durability, no compromise. The 6mm heel to toe drop hits the sweet spot for long-distance comfort in what is Inov-8's most cushioned shoe to date, and ADAPTER-FIT technology in the uppers delivers a supportive fit that adjusts to the natural movements and swelling of the foot when running long distances. Lightweight, breathable air mesh materials further aid a soft, natural feel without compromising on durability.

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, with 35 multi-directional 4mm deep lugs on each shoe meticulously shaped and positioned to improve both propulsion at the front and braking at the rear 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.
