The Red Wing Shoes Iron Ranger 3366 Black Boundary is a Red Wing Shoes Women style from the Core Collection. The Core Collection features the most popular styles from our men's collection, redesigned with cow hide and a softer insole, resulting in a boot that is much more comfortable. The Iron Ranger 3365 reinterprets the Iron Ranger from the Heritage collection, inspired by the Mesabi Iron Range in Northern Minnesota. The Red Wing Iron Ranger is easily recognized by its double leather toecap for safety and extra heel protection for better support. The Iron Ranger is built on a Vibram 430 Lug sole with a Goodyear welt and showcases the Red Wing Black Boundary premium leather from Red Wing Shoes' own S.B. Foot Tannery. The 3366 Iron Ranger comes with black-brown Taslan laces.
