Puma Safety Sierra Nevada EH WATERPROOF Mid Safety Toe Boots. Boots built for work. But with the comfort and style you won't find anywhere else but from Puma Safety. This pair is every bit as functional and work-tough as those big, bulky stompers you've got now, but these Sierra Nevada Boots look a lot cooler with their mid-height and hiking boot style, plus the comfortable athletic-shoe fit you love on weekends, but built for your 9 to 5. They're waterproof to keep you dry, plus, they're electrical hazard "EH" protected, oil, slip and heat-resistant and crazy-comfortable.
