About the shoe
The Inov8 Trailfly Max is a significant evolution for the brand, offering plush cushioning and a naturally responsive ride ideal for ultra distances and long days on firmer trails. Its combination of a wide, stable platform and best-in-class grip makes it a strong choice for runners seeking comfort without sacrificing confidence on technical terrain.
The graphene-infused outsole is highlighted as a major strength for grip and expected longevity. However, some reviewers express uncertainty about long-term durability, especially regarding upper materials and heel structure, as the shoe is relatively new and lacks extensive wear reports.

The Inov8 Trailfly Max is highly praised for its substantial cushioning, comfort, and grip, making it especially suitable for long runs and ultra-distance efforts on trails. Experts and users consistently highlight its plush ride, high stack FlySpeed Pro foam, and Graphene Grip outsole, which provide comfort and security over extended distances and technical terrain. The shoe's roomy toebox and breathable upper further enhance comfort for long outings and recovery runs. However, some reviewers note minor instability in the heel and a less locked-in fit, which can be noticeable during faster paces or technical descents. While the shoe is responsive for its category, its weight and maximal cushioning make it less ideal for tempo runs or racing, where lighter, more aggressive shoes are preferred. The Trailfly Max excels on hard-packed trails, gravel, and rocky terrain, but is less effective in deep mud due to its lug design.
- Exceptional cushioning with Flyspeed Pro foam keeps legs fresher over ultra distances and long training days
- Graphene Grip outsole delivers outstanding traction and durability, even on hard-packed or technical trails
- Wide forefoot and NATURALFIT shape allow toes to splay naturally, enhancing comfort and stability for extended runs
- Secure midfoot lockdown prevents foot movement inside the shoe, boosting confidence on uneven terrain
- Some runners question long-term durability, especially with the new foam and upper materials
- Higher stack height and maximalist build may reduce ground feel for those preferring a more connected ride
