2 sources · 2 reports
Inov8 released the TrailFly Pro, a new member of the TrailFly series, during UTMB week. According to an iRunFar trail running review dated September 29, 2026, the shoe is priced at $195 and weighs 233 grams (8.2 ounces) per shoe in a US men's size 9. On October 5, 2026, Believe in the Run published a hands-on report stating the shoe weighs 7.9 ounces per shoe, with a midsole stack of 34mm in the heel and 28mm in the forefoot, a 6mm drop, a price of $195, and an October 2026 release; the reviewer said its supercritical TPEE midsole balances rebound and cushioning, its forefoot fit is relatively wide, and it suits tempo runs on medium-hard terrain, but the G-Grip outsole lugs are relatively wide and lack bite in sand and loose dirt, and the upper is overall soft, lacking plate-like structural support. Earlier reports said it weighs 233 grams (8.2 ounces) per shoe, while later reports said it weighs 7.9 ounces per shoe.
Story reports
The Inov8 Trailfly Pro trail racer weighs 7.9 oz, with a 34mm heel and 28mm forefoot (6mm drop), priced at $195 and available October 2026. The reviewer says its supercritical TPEE midsole balances energy return and cushioning, and the foot-shaped last offers a wider forefoot for moderate terrain at uptempo efforts. Drawbacks: the G-Grip outsole lugs are too broad for sand and soft dirt, and the shoe is very flexible with no plate structure.
