Built on a brand-new anatomical shape and designed to let you fly over hard ground and rocky terrain, the Inov-8 Trailfly Speed in Black/Fiery Red fits snugly at the heel, then widens to let your toes splay at the forefoot for the perfect fit over technical terrain.

The Inov-8 Trailfly Speed is perfect for your faster paced training, from fartleks to tempo and speed workouts, due to its light design, and agile build. POWRFLOW PRO combines with a BOOMERRANG footbed to give you just right levels of bounce and energy return. Graphene enhanced rubber in the outsole gives a grippy yet durable hold, while the 4mm lugs have been designed to improve grip and shed debris quickly. Enhanced from previous Trailfly models, the GRAPHENE -GRIP outsole now has even better grip in wet conditions.
