The Clarion GTX is another time-tested classic. Developed in the 1990s by a small team looking to create the next Vasque breakthrough, the boot was a game-changer. The Clarion GTX delivers on a long-standing promise of comfort, support, and authenticity. The boot remains popular today as a rock-solid, time-tested option for more traditionally-minded backpackers. The boot has 2.4mm waterproof nubuck and nylon uppers, a dual density EVA footbed, molded PU midsole, a Vasque Tri-V Lug outsole and Gore-Tex for durable waterproofing.
