Secure Grip  : We've improved the outsole of Quest 4D 3 GTX with a new lug design for better grip on all surfaces. GORE-TEX keeps your feet dry -from the outside as well as from the inside. 4D Advanced Chassis™: This stable chassis construction harnesses two different midsole components for enhanced foot control and active comfort. Contagrip® TD: For maximum traction on mixed terrain and extended durability, Contagrip® TD combines a deep, aggressive lug pattern with our most durable compound.   EnergyCell - A high performance EVA foam that provides shock attenuation. Nubuck leather - Quality full-grain leather material for longer wear and durability. Water Repellant - Waterproof material remains unaffected by water even when under pressure. Waterproof footwear completely prevents water from entering it through the upper. Mesh and textile lining - A soft, breathable lining for extreme comfort. Gusseted tongue - The tongue is connected to the upper on both sides, preventing debris from entering the shoe, and keeping the tongue centered. Protective toecap - A protective piece of rubber, leather or synthetic material over the toe area. SensiFit™ - SensiFit™ cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around the foot. Protective mudguard - A wrap of leather, synthetic or rubber around the base of the foot that protects the lateral and medial sides of the foot. Molded OrthoLite® - Molded to match the contours of your foot, this OrthoLite® insole provides superior cushioning, as well as breathability and durability, to upgrade the comfort and performance of our footwear. Lace locker - A locking eyelet between the forefoot and ankle eyelets that locks the laces in place, enabling independent and precise adjustment.
