High-performance footwear provides layers of protection

| By Mary Page Bailey and Gerald Ondrey

The Philadelphia Wellington heavy-duty workboot (photo) is built to withstand tough work environments, while also keeping feet comfortable. The Philadelphia Wellington features a full-grain, waterproof leather to help resist the damaging effects of many chemicals, including oleic acid, urea, sodium chloride, ammonium hydroxide and more. The boots are designed with left and right asymmetrical, non-metallic carbon-fiber toes, which are said to be 15% lighter than steel. The outer sole is oil- and slip-resistant, and it also heat-resistant up to 300°C (572°F). Furthermore, electrical-hazard- or electric-shock-resistant footwear provides a secondary source of protection in case the user accidentally comes into contact with live electrical circuits. The boots are also equipped with a polyurethane midsole and are lined with a moisture-wicking mesh textile. — Keen Utility, Portland, Ore.
