A non-metallic safety toe, electrical hazard (EH) protection, puncture resistance, and slip resistance meet ASTM F2413-24 (I\/C, EH, PR, SR), plus full CSA Grade 1 (ESR rated, PR) certification — and the completely non-metallic build (toe and shank) makes it metal-detector-friendly. Red Wing waterproof full-grain leather and the three-layer Waterproofing System keep feet dry and extend high up the calf for extra protection, while 800g 3M™ Thinsulate™ Ultra insulation keeps feet warm even in damp, cold conditions. A Swen-Flex® non-metallic puncture-resistant insole adds underfoot protection, and the Vibram® Galactic Fire and Ice outsole delivers best-in-class slip, oil, gas, and chemical resistance across extreme temperatures.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKing Toe® fit — 44% more toe room than standard
