For professional use, our industrial grade Hoffman Pro-Series Pacs are our best selling boots— and for good reason. Less bulky than traditional felt pacs, the Pro-Series is an ideal boot for a wide variety of outdoor activities, weather conditions and terrain. While other companies seem to be lessening the quality in their rubber bottoms, Hoffman’s Pro Series waterproof, pure rubber bottom is simply the toughest on the market. The crack-resistant rubber features a steel shank for arch support and a rip-stop material built into the walls of the rubber for unbelievable toughness. Four sole choices are available depending on the conditions you are in. See more details and sole choices by clicking on boot. Made in Kellogg, Idaho.
