The Sambar Loop waterproof collection is game for all of the weekend's challenges. Hydro-Shield waterproofing substances are tanned into the full-grain leather uppers, and special seam-sealants help keep feet extra dry in wet weather. adiPRENE® by adidas cushioning on the inside protects the heel at impact, while a CMEVA midsole provides lightweight shock absorption for reducing foot and leg fatigue. Delivering extra stability is the external heel counter, which prevents excessive rear foot motion, and the rubber outsole, maintaining a durable grip on a variety of surfaces, with added flex grooves for forefoot flexibility. Reflective details mean enhanced visibility, ideal for that nighttime hike back to base camp.
