The Inov-8 TrailFly Speed is a trail running shoe designed for firmer tracks, emphasizing a more natural, anatomical fit and greater foot function. Unlike its counterparts, the TrailFly Speed focuses on providing a good level of ground feel and flexibility, which enables quicker movement across hard-packed trails without the hindrance of less flexible, heavily cushioned shoes. It shares the same anatomically shaped last as the Inov-8 Mudtalon series, featuring a snug heel, a well-fitted midfoot, and a broad, rounded toe box that allows the foot to spread upon impact, enhancing agility and ease in navigating complex terrains.

The shoe is constructed with a single piece of air mesh for minimal seams, a flexible yet structured heel, and a gusseted tongue to keep debris out. The lacing system is designed to secure the foot, providing stability on uneven grounds and steep descents. Its Boomerang insole and Powerflow Pro midsole offer a responsive cushioning that allows for a natural ground feel and efficient energy return, complemented by a Graphene-infused sticky rubber outsole for optimal traction. This setup results in a shoe that supports the foot’s natural function, promoting a dynamic and propulsive running experience ideal for exploring rugged trails.

GRAPHENE-GRIP RUBBER OUTSOLE

4mm GRAPHENE-GRIP rubber studs are carefully positioned in multiple directions to improve grip, shed debris quickly, boost propulsion off your toes and help you brake at the heel. The graphene-enhanced rubber has also been improved to give extra grip in wet conditions, when compared to previous models.

POWERFLOW PRO MIDSOLE

A bouncy, cushioned ride that retains high levels of responsiveness is provided by the new POWERFLOW PRO foam midsole. This amazing underfoot comfort and propulsion is built in a way that still allows for the ground-feel you need when running over uneven, hazardous terrain.

AIR-MESH UPPER

A single piece of air-mesh material, making the shoe highly breathable, comfortable. Over the top of the air-mesh, thick MET-CRADLE strips connect the midfoot to the heel, creating a locked-in, secure feel when you tighten your laces.

BOOMERANG FOOTBED

Preserve your energy on long runs with the BOOMERANG Footbed. The insoles feature hundreds of foam beads that compress and spring back for 40% energy return during your stride. Perfect for longer runs where maximising every bit of energy counts.

ANATOMICAL FIT

The TRAILFLY SPEED hugs the natural contours of your foot, locking you in at the heel and then widening at the toes. This anatomical fit allows your feet to splay and feel the ground, while still giving you that secure feel that you need on technical trails.
