Red Wing 1411 Heritage Boots | Size 10.5 D The Ultimate Professional Tool for Cold Concrete & High-Volume Floors These are my boots that I used working long shifts in the refrigerated section of a grocery store: The Red Wing 1411 is a heavy-duty, 8-inch workhorse designed for maximum durability. Engineered for those spending 40+ hours on hard, cold surfaces, these boots offer a specialized balance of thermal protection and structural support. Technical Specs • Leather: Premium Waterproof Oiled Full Grain; resists moisture and chemicals. • Insulation: 400g 3M™ Thinsulate™ Ultra for warmth without the bulk.  • Safety: EH (Electrical Hazard) Rated. • Outsole: Legendary SuperSole®—oil, gas, and chemical resistant with superior traction.  • Construction: 8\" height for ankle stability; fully waterproof system. Investment Grade Gear • All-Day Comfort: SuperSole® technology specifically reduces foot fatigue on hard surfaces. • Long-Term Value: These are fully resoleable by Red Wing for decades of use. • Condition: Properly broken in, deep-cleaned, and conditioned.
