Stack Height (Heel / Forefoot) : 25mm / 22mm. Heel-to-Toe Drop : 3mm. Durable mesh and PU-printed upper features water-drainage ports for faster and quicker drying. Padded collar and fully-gusseted tongue assists at keeping debris from entering the shoe and stay comfortably in place. Traditional lace-up closure.

Vibram XS Trek outsole delivers unbeatable grip, traction, and durability. Deep and spaced lugs provide improved underfoot traction in mud.
