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.
A soft, non-abrasive, hydrophobic material that wicks perspiration away from the foot, enabling the skin to remain cool and dry.
A hardy, Polyurethane Bump that’s directly moulded as part of the midsole.
These boots are stitched with strong, heat resistant Kevlar® aramid fibre thread which is five times stronger than steel (weight for weight), and tolerates heat and sparks better than conventional threads.
A classic fastening for snug, well-fitting work boots.
Boots made from high quality, long-lasting leather, including Nubuck, Full-Grain, TECtuff®, Suede and more.
With heat resistance to 300°C, safety boots with Steel Blue’s Nitrile Outsole are great for working in very hot conditions.
Our Ortho Rebound® Footbed is uniquely designed to mould to the exact shape of your foot, supporting your arch and reducing foot fatigue.
Strategically placed high-tech Poron® pads are placed in the sole and under your foot’s peak stress areas. We included Poron® in our Trisole® Comfort Technology, which is now the benchmark for safety boots.
All Steel Blue footwear is designed to exceed the Slip resistance requirement in both the AS 2210.3 and EN ISO 20345. Our boots are rated as SRC which means that the footwear has been tested in laboratory conditions on both a ceramic tile floor with a Sodium Laureth Sulfate solution (SLS) and on a steel floor with Glycerine.
Made from hardened steel for premium toe protection.
Steel Blue’s unique soling system cushions your feet, knees, hips and lower back from day-to-day fatigue, for whole-body support.
A treatment during the manufacturing process provides water resistance so that water is repelled from the surface.
Lace Up for comfort, then use the side zips for quick access.
