We have expanded our original Dry-Strike collection into the Dry-Strike Srx. This 3 twin gore slip-on composite toe shoe is built with full grain leather on our non-marking oil- and slip-resisting Dry-Strike outsole perfect for added grip around the marina or factory floor. This non-metallic shoe also features a light and flexible cement construction with a removeable Esd Shield footbed which provides protection from heel-to-toe that doesn t degrade over time while providing the highest level of Esd protection, comfort, and performance. This shoe meets Astm F2413 protective toe and static dissipative classifcation - valid only with original footbed..
