The lightweight GEL-FUJITRABUCO™ SKY trail shoe is a recommended choice if you want to run fast off-road. Developed with three-time UTMB winner Xavier Thevenard, this shoe’s design approach focused on weight and drainage. It has a flexible plate under the forefoot that allows runners to move quickly over rough rock and root-strewn trails. The upper is reinforced along the base of the shoe to help keep trail debris from entering the interior. Additionally, the GEL-FUJITRABUCO™ SKY trail model features elastic laces for added comfort and easy adjustments on the fly. A key design element is the placement of small holes in the sole and sockliner, which use the natural motion of the foot to quickly and efficiently push water out of the shoe and away from the foot. The outsole features a trail-specific traction pattern with lugs precisely oriented on the medial side for the uphills and under the heel and lateral side for the descents. The outsole rubber formulation is also specifically designed to grip even better on wet trail surfaces.
