After building work boots for 90+ years, Danner® has got their game honed. Insulated Steel Yard Boots are the result of all those decades of innovating and improving to take the hard knocks and hazards of the jobsite in stride. The tough-as-nails full-grain leather upper is backed up by Danner® Dry waterproof protection and lightweight-yet-intensely-warm Thinsulate™ insulation. Underfoot, Danner’s exclusive Comfort System platform combines the ideal combo of cushioning and support. Steel toe meets or exceeds ASTM F2413-18, I/75, C/75 EH standards – essential when a rogue log or an engine block lands on your toe. Plus they're ASTM Electrical Hazard rated to protect from electrical currents up to 18,000 volts. Supportive Danner Steel Yard wedge sole clings tight to slick surfaces. They’re the boots you need to take a stand against smashing, shocks and slips.
