You are exposed to freezing cold temperature? You won’t be able to work without the Fighter! Made of waterproof leather, this winter boot meets CSA and ESR standards. Its PU shell makes it lighter than a rubber boot. Its full length natural rubber outsole makes it sturdy, adherent, stable, resistant, and anti-skidding even during the most freezing cold weather of our nordic winters! This boot has a high performance removable six densities “IFELT +” liner, offering a comfort zone up to -103°F. This boot is waterproof and very warm.
