Quest 4D 2 GTX makes backpacking just a little easier. This lightweight but supportive boot borrows from running shoe technology to provide stability and comfort while keeping the weight down. And a high top cuff and full waterproof bootie ensure protection all year long. Developed through research and experience in trail running, Sensifit wraps around the midcourt area to ensure a snug, comfortable fit for every foot shape. Salomon's 4D advanced chassis guides the foot even on the roughest terrain, reducing fatigue for all trek comfort. Material: Nubuck Leather, Textile.
