Built for hazardous duty, the Propper Series 100 Side Zip Waterproof Composite Toe Tactical Boot features an ASTM F2413-11 rated safety toe that meets or exceeds I/C 57 Impact and Compression Resistance and EH Electric Hazard. The waterproof leather and 1000D Cordura upper can be pulled snug with the quick and easy YKK Side Zippers and NATO speed lace system. A special gusset behind the zipper helps keep water out while the triple density rubber foundation and an arch made from a durable compound will hold up to the rigors of fast-roping.
