The ASICS GEL-FujiTrabuco 8 GTX is the 8th version of the FujiTrabuco and this particular iteration features GORE TEX on the upper making the shoe waterproof and ensuring that your feet stay dry when worn in tougher weather conditions. It features the same overlays as the FujiTrabuco 7 but with an increased level of flexibility, and has Flytefoam cushioning in the EVA midsole, GEL technology at the heel, the Dynamic Duomax system for stability, and is finished off with a grippy trail specific outsole.
