Red Wing and Irish Setter are both brands owned by the Red Wing Shoe Company. While Red Wing is the parent brand, Irish Setter is a line of specialized work boots produced by the same company. The main distinction lies in the purpose and design of the boots. Red Wing offers a broader range of work and casual boots, while Irish Setter is specifically focused on providing high-quality work boots, often with advanced features for specific industries such as hunting or heavy-duty labor. Essentially, Irish Setter is a specialized subset within the broader Red Wing brand, catering to specific needs and preferences.
