Ridge Outdoors' new AIR-TAC Mid Side Zipper has all the perks of other Ridge boots combined. The developer of the first tactical air heel system has created this lightweight (20 ounce) boot, with slip-resistant outsole and one-time lacing. After that, it's easy on, easy off with one swift pull of the zipper, and because of it's unique rip-stop nylon material, this boot offers top protection against tearing and fraying. Its vapor-wick lining absorbs moisture away from the feet to help keep them dry. EMTs, law enforcement and firefighters will find comfort, right out of the box, in a large range of sizes.
