Imagine yourself charging down a rugged trail, heart pounding, breath rhythm steady - and beneath your feet, you’re wearing the Inov-8 TrailFly Speed V2 Men’s Shoes that feel less like gear and more like an extension of your body. These are fast trail running shoes born for the days when you’re chasing time, chasing views, chasing that feeling of flying. 

With a sleek, low profile silhouette and a balanced 4mm drop, the ride feels grounded yet springy - just enough lift for comfort, while keeping you connected with the earth. On the upper, tougher, more durable KPU overlays wrap your foot in rugged protection, so even when the terrain fights back with rocks, roots or gravel, you don’t pull back - you run on. 

The META-CRADLE strips create a secure feel from midfoot to heel, and the NATURALFIT shape lets your toes relax and splay comfortably. The Boomerang footbed provides shock-absorbing compression and springy rebound to preserve your energy and apply it into forward momentum.

The standout upgrades are the updated POWERFLOW PRO midsole, delivering responsiveness in a stable ride, and the enhanced G-GRIP graphene-infused rubber in the outsole, optimising your traction and slip resistance on wet trails. With 4mm rubber lugs, you’ll glide over rocky terrain and hard grounds smoothly and confidently, and get more mileage out of your best trail running shoes for speed workouts and racing.
