If you want to run fast off-road, the lightweight GEL-FUJITRABUCO SKY trail shoe is for you. 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, allowing 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. Finally, 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 push water quickly and efficiently 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 wet trail surfaces.Small holes in the sole and sockliner, which use the natural motion of the foot to push water quickly Outsole features trail-specific lugs for better traction on off-road surfaces GEL technology to offer a cushioned underfoot.
