Durability, safety, and comfort... all of these factors were considered when RockyA(R) constructed AlphaForce Zipper Composite Toe Duty Boots. To create a durably tough exterior, Rocky used full-grain leather and 1000 denier nylon (superior strength). A side zipper allows you to easily get these boots on and off. It's covered with a VELCROA(R) strap. While you're on duty, Alpha Force boots keep your feet safe. They have a composite toe that meets ASTM standards for impact and compression. The boots also meet ASTM F2413-11 Electrical Hazard standards. Although these Alpha Force duty boots have a tough exterior, the Air-Port(TM) cushion footbed supports and cushions your feet each time you take a step. It also circulates air within these boots. The RigiTrac(TM) outsole won't leave marks, and its slip-resistance helps you keep your balance while on duty. With all of these great features, this Rocky Alpha Force is the right duty boot for you!

Compression testing determines the amount of static pressure a steel/composite toe cap can withstand.
