Men's CSA Fort Mac Boot (Steel Toe)

$220.00

  • Style #1009044
  • Fit Tip: Most customers find this style is true to size! Fit Guide
Please choose a size!

Twelve-hour days, tough jobs and rugged terrain, this bomber boot takes on anything. Built tough, it utilizes the patent-pending KEEN.Welt’s incredibly durable, flexible construction. This boot hangs in for the long haul and keeps you comfortable when you're on your feet all day. Meets CSA Z195-09 Grade 1 standards.

  • Non-continuous Goodyear Welt construction for enhanced durability under extreme working conditions
  • Left and right asymmetrical steel toe
  • Non-metallic, punture-resistant midsole plate—CSA Certified
  • TPU shank for midfoot support
  • Locking metal hooks and lacing eyelets
  • Abrasion-resistant Tough Tec leather
  • 90 degree heel
  • *Cleansport NXT™ for natural odor control
  • Meets CSA Z195-09 Grade 1 standards for protection

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.
