Inov-8 Mens Trailfly Speed

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. For launch, the TRAILFLY SPEED is available in Wide Fit, giving runners our 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, thick MET-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.
