Upper: An anti-gravel tongue features a gusseted construction that prevents debris from entering the shoe. Heel Clutching System is an exoskeleton heel counter that provides improved support and creates an improved heel fitting environment. Lace pocket on the tongue enables the laces to be tucked in where they will be unexposed. Lightweight mesh with synthetic overlays provides breathability with enhanced durability and support.

Midsole: Forefoot and rearfoot GEL® cushioning systems attenuate shock during the impact phase and allows movement in multiple planes as the foot transitions through the gait cycle. Solyte® midsole material provides enhanced cushioning and durability while weighing less than ASICS' standard EVA and SpEVA. Rock protection plate provides protection against stone bruises.

Outsole: WET GRIP® outsole is a special blend of organic and non organic compounds, designed to enhance traction, even on wet surfaces. AHAR® (ASICS High Abrasion Rubber) is placed in critical areas of the outsole for maximum durability. Aggressive lugs ensure optimal traction out on the trails.
