Product Description Nano safety toe, waterproof, EH rated — 11-inch pull-on work boot with barnyard-acid resistant leather and sustainable materials throughout The Twisted X UltraLite X is an 11-inch pull-on work boot built for farmers, ranchers, and anyone who works around livestock, chemicals, and wet ground. It meets ASTM F2413-24 I/C EH SRO for nano composite safety toe impact and compression protection, Electrical Hazard resistance, and oil/wet slip resistance — all in a build that's roughly 20% lighter than a traditional work boot. BarnShield leather resists barnyard acids, a waterproof lining keeps feet dry, and the Blend85 footbed with ecoTWEED lining delivers all-day cushioning made from recycled materials. Classic western square-toe style, ag-tough protection, and a real sustainability story under the hood.
