A debris shield system with a combination of rubber sidewall panels and/or PU dots on the toe and heel add protection in critical areas.

Self adjusting laces means no stopping in the middle of your run to re-lace your shoes.

Features a trail strike last which is built to accommodate changes the foot endures over long distances. This provides the right amount of freedom of movement to enhance the body's natural stability. Anatomical shaping around the foot allows the toes to spread out upon footstrike, maximizing balance. A sculpted footbed holds the foot in place on ascents and descents. A squared toe box gives extra room for toes, and acts as an additional protection bumper. The vertical motion outsoles multidirectional design provides extra traction and stability on steep and rugged terrain.

Features the PreciseFit™ System a patent-pending adjustable insole system that can be individually customized for a better fit. PreciseFit™ technology introduces a scientifically developed, tested and proven tri-fit system based on variations in forefoot girth, the number one reason for fit and comfort problems. Each pair of shoes comes with a system of different thickness footbed inserts that lock onto a removable footbed. A customized fit is the result.

One box fits full and half sizes in narrow, medium and wide widths. Even addressing two different size feet. A stabilized heel cradle locks the heel in place minimizing movement and friction while an anti-microbial footbed keeps your shoes fresh. Features Gripstick™ rubber traction which is an exclusive high-grip compound that offers extra traction on slick surfaces, such as wet rocks, snow and ice.

Trail Claws improve traction by digging into loose dirt or interlocking onto hard, jagged rock. When compressed, the individual claws create even more surface contact and work in concert with the surrounding claws to provide additional traction.
