The Inov-8 TrailFly Ultra G-Series 300 Max is a revolutionary trail shoe featuring the world’s first graphene-enhanced foam: G-FLY. Pioneering a new way for cushioned ultra running shoes, TrailFly Ultra G 300 Max uses GRAPHENE-GRIP rubber for the world’s toughest trail traction, while the supportive upper fit adapts to the natural changes of the foot when running big miles.

The TrailFly Ultra G-Series 300 Max features:

  • ADAPTER-FIT upper - provides a lightweight, breathable fit that’s still supportive and durable enough for ultras. The roomy toe box allows your feet to swell over long distances, while welded overlays protect your heel and toes from trail debris.
  • BOOMERANG insole - boasts a 40% increase in energy return versus the previous footbed.
  • G-FLY graphene-enhanced 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.
  • Agile ADAPTER-FLEX groove - 10mm deep groove that allows the shoes to adapt and react to uneven terrain: a first for max-cushioned shoes!
  • G-GRIP outsole - the world's toughest grip: graphene-enhanced rubber that's 50% stronger, 50% more elastic and 50% harder wearing than traditional rubber to deliver the world’s toughest grip on hard-packed trails.
  • 35x 4mm lugs - provide front propulsion and rear braking, with water dispersion channels and rubber dimples for extra grip on slippery surfaces like wet rocks.

Agree too narrow and low cut up front

, 17 July 2024

I’m an Inov buyer and bought heaps of 250’s which had no probs with width. The 300’s have a pointy toe box and narrow forefoot. Don’t like returning shoes so I cut and patched the toe box and forefoot to make em work. It looks ugly but got them running OK. Been down the road of Altra lone peaks and did not like the arch and lateral support humps and bumps. I’m pure neutral in every way.

Hi Dennis, Thank you for your feedback. This shoe is marketed by Inov-8 as wide, but we've updated our listings now based on your experiences. Sorry to hear about the issues you had getting a wider fit from them, hope you have them working for you now. Please let us know if there is anything else we can help you with.

A miss

Shoe fit is obviously completely subjective but the G300 max is sold as a "wide fit". It's not. I should have returned them immediately, but was sold on the marketing hype and thought I'd give them a few runs. The forefoot shape is euro-style narrow, and there's not even much overall toe box volume. With this kind of stack height, you also had better be blessed with perfect gait because stability is compromised; made worse by the narrow forefoot. It is a good transition shoe (feels pretty good on the road for example) but who wants to own the weight penalty for that over better shoes in that category? Graphene... mmmm. I am guessing it may ultimately make for a more durable outsole. The price you pay for a less tacky material is less grip on rock. For muddy, loamy conditions, these shoes would be great. For a lot of Australian conditions (loose rock more than mud), I'd suggest the grip is only so-so at best. Two star. I used to love Inov-8 shoes. The fit in recent years has become restrictive and the upper materials offer less mid foot support than competing shoes. At this price, you expect something great. Unfortunately why're only average at best. If the foot shape works for you, and you love the brand, I'd go for the 270s over these. Wildfire are great. Good prices, good service and their $3 'try two' is a fantastic program. Use it for these shoes.

Hi David, Very sorry to hear you weren't happy with the fit of your new Trailflys! This model is Inov-8's '5' width, the widest they offer at the moment. We've found '5' width shoes to be wider than standard runners, but closer to a 2E rather than extra wide 4E for men. For a wider fit, I would recommend considering an Altra Lone Peak or similar. We're happy to provide assistance with fit via email or phone should you need it, and of course a free exchange if you're not happy with a shoe prior to wearing it outside. Warm Regards, Wildfire Team
