Built for hazardous duty, the Propper Series 100 Side Zip Water resistant Composite Toe Tactical Boot features an ASTM F2413-11 rated safety toe that meets or exceeds I/C 57 Affect and Compression Resistance and EH Electric Hazard. The Water resistant leather and 1000D Cordura upper will also be pulled snug with the fast and easy YKK Side Zippers and NATO speed lace system. A special gusset at the back of the zipper is helping keep water out at the same time as the triple density rubber foundation and an arch constituted of a durable compound will hold as much as the pains of fast-roping.
