True to size: This footwear is true to size for a supportive, comfortable fit. Combining a 3D carbon fibre footplate, midsole rocker geometry and SurfaceCTRL™ grip, our new VECTIV™ technology is designed to maximise energy on the trail. And the Flight Guards are the most responsive waterproof shoes in our 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. The uppers are made with breathable-waterproof FUTURELIGHT™ technology enhanced with durable Spectra® yarn and feature a zipped gaiter for protection even in snowy conditions.
