Steel Blue is committed to producing durable, comfortable work boots using premium, ethically sourced leather. They obtain their leather exclusively from tanneries that are members of the Leather Working Group (LWG), ensuring adherence to stringent environmental standards. As of 2024, 90% of their leather comes from top-rated suppliers, with a goal to source exclusively from LWG Gold-rated tanneries by 2025. Additionally, Steel Blue emphasizes sustainability by ensuring all leathers are by-products of the food sector, minimizing waste and promoting ethical practices.

Their commitment extends to reducing energy, water, and chemical usage throughout their supply chain and manufacturing processes.

These initiatives reflect Steel Blue's dedication to environmental responsibility and sustainable manufacturing.
