The Rocky Iron Skull Collection is the superior boot collection for those grueling days in the field or on the job. This boot is a pull on, eleven-inch, waterproof boot with an internal metatarsal guard guaranteed to keep your feet dry and protected. We've developed the Ram Ridge, a rugged Tpu heel counter that will make kicking these boots off a piece of cake. Each Iron Skull boot comes with a Rocky EnergyBed footed that absorbs shock and always returns to its inherent shape. Flex-grooves also conform to the articulation of your foot, making you confident and comfortable on your feet for hours on end. The rugged rubber outsole is oil and slip resistant, making worries about slick surfaces a thing of the past. Safety is certain in this boot - it meets both the Astm F2413 protective toe classification and electrical hazard standards. Adding to the comfort and protection is our brand new waterproofing technology, Rocky Vp.
