Men's CSA Philadelphia+ 8" Insulated Waterproof Boot (Carbon-Fiber Toe)

$240.00

  • Size Guide
Please choose a size! Please choose an inseam!

This insulated boot steadies, protects and keeps feet comfortable with its ¾ welt construction and heel stabilizer system, KEEN Luftcell aerated PU midsole, and KEEN.POLAR TRACTION micro-cleat grip outsole.

  • Left and right asymmetrical, non-metallic carbon-fiber toes offer unobtrusive fit and are 15% lighter than steel
  • KEEN.DRY waterproof, breathable membrane
  • Full-grain waterproof leather
  • Oil- and slip-resistant non-marking rubber outsole
  • 600G Insulation for extra warmth in colder environments
  • Electrical hazard (EH) or Electric Shock Resistant (ESR) footwear provides a secondary source of protection in case of accidental contact with live electrical circuits
  • KEEN.POLAR TRACTION: Micro-glass fibers create a "micro cleat" effect for increased ice traction*
  • Non-metallic, flexible woven-textile puncture resistant midsole plate - ASTM/CSA certified
  • 3/4 Goodyear welt construction for enhanced durability and flexibility under extreme working conditions
  • KEEN Luftcell PU midsole, infused with air for weightless comfort

We've carefully selected leather uppers designed to last. Then again, if you're wearing your KEENs daily, they won't always be scuff and dirt-free. To treat day to day wear and tear, especially on lighter color leathers, we recommend using a leather cleaner and conditioner, found at most footwear dealers and/or shoe repair shops.

  • This insulated boot steadies, protects and keeps feet comfortable with its ¾ welt construction and heel stabilizer system, KEEN Luftcell aerated PU midsole, and KEEN.POLAR TRACTION micro-cleat grip outsole.
  • KEEN.Dry
    A proprietary waterproof, breathable membrane that lets vapor out without letting water in.
  • KEEN.Warm
    Who knew charcoal bamboo could create something that keeps your feet warm? But it makes KEEN.Warm—a lightweight insulation that provides warmth where you need it most.
  • Barnyard Proof
    Superior leather resists the damaging effects of oleic acid, urea, sodium chloride, and ammonium hydroxide in order to extend the life of your boot.
  • Puncture Resistant Plate
    Puncture resistant boots help reduce the possibility of injury caused by sharp objects that can penetrate the bottom of a boot. KEEN Utility uses a non-metallic, woven midsole plate that meets ASTM and CSA standards.
  • Left and Right Asymmetrical Safety Toe
    Uniquely anatomically correct steel, aluminum, & composite toe designs provide a roomier toe box and maximum comfort. Meets ASTM F2412-11 and F2413-11 I/75 and C/75 Standards.
  • Electrical Hazard
