The Red Wing Shoes Chelsea 3455 Black Boundary is a Red Wing Shoes Women style from the Modern Collection. The Modern Collection features our most classic models, completely redesigned for a much more sophisticated and feminine silhouette. The Chelsea reinterprets the Chelsea Rancher from the heritage collection, originally developed for sheep ranchers in the United States. The Red Wing Chelsea Rancher was the perfect match because ranchers needed sturdy but comfortable shoes while guiding their flocks. The Chelsea is built on a Vibram Mini Lug outsole with a three-quarter Goodyear welt. The Chelsea showcases the Red Wing Black Boundary smooth finished premium leather from Red Wing Shoes’ own S.B. Foot Tannery.
