PRODUCT INFO
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.

Size Guide
We know that finding the right shoe size can be tricky!
We’d recommend looking at the size guide which shows the approximate length of each size’s insole in centimetres.
If you already have a hiking boot, running shoe, or training shoe that fits you well, you could measure the length of the shoe’s insole and match this with the size guide.
Alternatively, you can measure the length of your foot and add between 1 and 2cm to find the correct insole length. It is hard to be exact here, as sizing is so personal – but in hiking boots, running shoes or training shoes, we’d recommend having at least 1cm of extra space beyond the end of the longest toe to ensure comfort.
