Built with the Special Operations warrior in mind, the Rocky S2V is one of the most innovative combat boots available. Made out of MIL-SPEC materials, the S2V is flame retardant, has anti-microbial properties built into the interior of the boot which combat foot rot and infections, and has a built in fast rope guard on the inside of the boot. The materials do not absorb any water, and built in one way drain holes quickly drain the S2V. The boot is finished off with a water/oil resistant Vibram sole and is completely made in the U.S. leather insteps are ASTM tested by exposure to multi-directional abrasion until clear damage is done. The S2V SuperFabric withstood 35,000 cycles, which was 1.9 X more cycles than Keprotech 2, and 14.5 X more cycles than Cordura. This translates to supreme resistance to cuts, abrasions, punctures, rope burn, animal bites, and rot.
