Founded in 2003 in Portland, Oregon, KEEN develops footwear focused on outdoor use and everyday function. The brand is known for hybrid designs combining the structure of a shoe with the openness of a sandal, often featuring protective toe caps and durable rubber outsoles. Core styles include sandals, trail shoes and slip-on silhouettes constructed with quick-drying uppers and grippy tread patterns. KEEN also emphasizes responsible production through material choices and long-wearing construction. Today, the brand continues to produce utility-driven footwear designed for varied environments and daily wear.
