The CSA Philadelphia 6’’ with internal metatarsal protection keeps feet in reliable comfort, protection and support. Built tough from every angle, the heavy industrial designs are crafted with Barnyard-Resistant leather, a super-durable, waterproof material resistant to caustic chemicals including alkali, sulfuric and oleic acids, calcium hydroxide, and other barnyard acid.
The boots are also armed with KEEN.Dry, a waterproof breathable membrane lining that allows moisture out but never in. A 3/4 welt construction and heel stabilizer system provides excellent torsion stability over uneven ground and the most durable footwear construction on the market.
Heavy design does not translate to dragging, uncomfortable feet thanks to left- and right-specific, asymmetrical non-metallic carbon-fiber safety toes that are 15% lighter than steel and offers a roomier, more unobtrusive fit. Comfort goes the extra step with a KEEN.Luftcell air-injected, dual-density PU midsole with 100,000 air bubbles per cubic centimeter for next-level cushion.
Underfoot, the Philadelphia builds on its brawn with an abrasion-, oil- and slip-resistant rubber outsole that meets ASTM Mark II non-slip testing standards and a heat-resistant rubber rated up to 572 degrees Fahrenheit.
