Redback Rescue Steel Toe ASTM Boots blend the comfort of a tennis shoe with the functionality of a work boot. This rugged steel toe boot features a 9-inch ankle with a quick-release zipper for easy on and off. A triple-padded collar maximizes comfort for your ankle and lower calf, while a full-grain leather upper can withstand anything the job throws at it. An oil, acid, and slip-resistant outsole provides a rock-solid grip on unpredictable surfaces and protection against electrical hazards. With an ASTM F2413-11 rated steel toe for maximum protection, the Rescue Boot is ready for a hard day's work.
