The 11 inch Waterproof Muddog Composite Toe EH Wellington Work Boot had an Ergo-Fit composite toe cap that allows your toes to have more wiggle room while still being protected. This boot meets the ASTM F2413 standards for protective toe and electrical hazard footwear. The rubber outsole is oil, slip, chemical, and abrasion resistant and is armed with the Georgia Waterproof System to keep water from seeping into your boots. The waterproofing is backed by a guarantee, so you can be confident when taking on that damp work day.
