The Quest uses a development of the 3D chassis which has been successfully used on Salomon trail running shoes, the 4D Advanced chassis has evolved with extended cushioning over the forefoot adding the comfort & stability needed in a hiking boot. Nubuk leather & nylon textile uppers provide durability, enhanced breathability & support & is backed by a full Gore-Tex lining for waterproofing & breathability. With plenty of internal padding the Quest is immediately comfortable & just begs to be taken on a long walk in the hills. Grip & security is provided by Salomons reliable & proven Contagrip sole unit which has directional lugs with different density to provide both grip & durability. All these features combined give for an incredibly light, stable & versatile boot.
