How do you take a best-selling boot like the Original S.W.A.T. classic 9-inch tactical boot and make it better? By adding a heavy duty side zipper to allow easy on and off. And best off all, they did it without changing the many comfort-enhancing and durability-building features of the original classic tactical boot. With the zipper you can jump in and out of these boots in a fraction of the time it takes to lace and tie them. Great for EMS/EMT, first responders, and other emergency, public safety and homeland defense personnel as well as those who just want an easy-on-easy off boot.
