The Inov8 TrailFly Speed Wide trail running shoes are designed for fast running on hard trails. Perfect for racing, tempos, fartleks and speedwork.
20 years in the making, the TRAILFLY SPEED brings together everything INOV8 has learned over the past two decades, culminating in the ultimate fast-feel running shoe for hard-ground trails. Whether you’re racing or training, it’s time to unleash your inner speed! With a new foot-shaped fit and exciting enhancements in grip, cushioning, comfort and protection, this new breed of beast is ready to meet the next generation needs of runners who like to tear up trails. Its sibling is the more cushioned, higher drop TRAILFLY, built for super-comfort running over hard-ground trails.
Built on a brand-new, anatomical shape, the Inov8 TrailFly SPEED hugs the natural contours of your foot. The shoe fits snugly at the heel, giving you that locked-in feel, and then widens to allow your toes to splay. This gives a comfortable, secure and responsive feel as you race over technical trail.
Perfect for faster paced training, the TrailFly Speed will help you nail those tempo, fartlek and speed workouts. Its lightweight design (just 270g on average across all sizes) means that you can race in it too.
With a 4mm drop, the shoe strikes the perfect balance between natural feel and cushioning. PowerFlow Pro foam provides just the right amount of bounce, working with a Boomerang Footbed to give you high levels of energy return.
The TrailFly Speed has 4mm rubber studs that have been carefully positioned in multiple directions. These studs improve grip, shed debris quickly, boost propulsion when you toe off and help you brake at the heel. The graphene enhanced rubber gives you harder-wearing, firm grip and traction over hard, rocky ground. The formulation of this rubber has been improved on previous TrailFly models too, giving you better purchase when conditions are wet.
Tame the trails in the Inov8 TrailFly Speed. The ultimate hard ground trail racing shoe.
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 Meta-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.
Shoe Tech & Benefits
New Shape & Fits
The carefully crafted new foot-shaped fit which features on all new Inov8 footwear in 2024 hugs the natural contours of the whole foot. It locks in at the heel for a confidence-boosting, secure hold and widens at the toes to allow the feet and toes to function naturally. This brings greater performance benefits and comfort levels for trail runners. Incorporated within the new overall shape are three new fits. The TrailFly Speed is available in Wide Fit, giving runners Inov8's widest platform in the toe-box and heel for extra comfort, especially over longer distances. A narrower Standard Fit version will follow.
Improved Grip
Hard-wearing rubber infused with the world’s strongest material – Graphene – has now also been enhanced with more stickiness. It means the newly shaped 4mm long lugs not only cut through loose trail and remain super-durable, but also give greater grip in wet conditions. The lugs are carefully positioned, pointing in multiple directions to shed any lingering debris, improve toe spring when running uphill and aid faster heel-breaking when running downhill. Underfoot flex grooves, including a new vertical one beside your big toe, give even more uphill spring, while bigger shaped lugs in high-wear areas further enhance the outsole’s lifespan.
Better Protection
Skip over technical trail and sharp rocks knowing the bottom of your feet are protected by the addition of a flexible Meta-Shank rock plate. Thanks to its flexibility, the plate still allows your feet to move naturally and enjoy some feel for the terrain underneath. At the front of the shoe, a toe guard adds further protection when you inevitably kick a rock.
New Cushioning
A cushioned, bouncy ride that retains high levels of responsiveness is provided by the new superlight 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 terrain. A new, lighter version of the 6mm thick Boomerang footbed features hundreds of expanded TPU beads that compress and spring back for more energy return and cushioning. This footbed now features more perforations to help water evaporate and transfer out of the shoe.
Outstanding Breathability
A single piece of air-mesh material forms the upper making the shoe highly breathable and comfortable with zero irritation to feet. Over the top of the air-mesh, light Meta-Cradle strips connect the midfoot to the heel, creating an even greater locked-in, secure feel when you tighten your laces. A gusseted tongue stops any debris slipping down past the laces and into the shoe.
