Combining a 3D carbon fibre footplate, midsole rocker geometry and SurfaceCTRL grip, the new VECTIV technology is designed to maximise energy on the trail. And the Flight Series Vectiv Shoes are the most responsive in the TNF elite trail running range. Light and energy giving they are tried, tested and trusted by our athletes. Made for ultra-distances, they’re incredibly durable thanks to Kevlar, polyamide and Matryx fabrics, and reinforced toe caps. The knit uppers are breathable and supportive and the 6mm toe-to-heel offset propels you into your next gait cycle.
