About the Gen II Program

The Gen II system created in conjunction with the US Department of Homeland Security, the Army’s Natick research center, and numerous other government agencies. The goal of the program was to develop garments that could offer optimal protection against the risks faced by modern wildland firefighters. Flame resistance was a priority, but a high emphasis was also placed on breathability to reduce the risk of heat stroke and exhaustion in warm environments.

The program set high standards, all of which are met or exceeded by the CrewBoss Gen II Garment System.

      Comfortable Shoes Right Out of the Box
      Size: 9, Color: Black
      I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

      Decent Shoes with Misleading Description (Not Leather)
      Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
      I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
