Light and comfortable, didn't hold up for a full season
Size: 11.5, Color: Black
Pros:boots were extremely light and comfortable. Cons: if you work in rocky areas like northern California you will only get 1/2-1 season on these. Mine lasted 6 months then the fabric ripped, the soles had holes all the way through to the middle, and the tread wore down til they were smooth slick rubber. If they cost $150-$175 I'd buy 2 pairs a season but at over $300 a pair there are much better options

I just purchased these boots 09/03/25 , let's see what these reviews are about? Why isn't their a direct website for the company? Quality and Durability.

Nice boot!!
Size: 8.5, Color: Black
Very comfortable. Built well and obviously high quality. Fits a little big, about a size larger. They are a little thinner/cooler than the Danner Wildland and Haix Missoula. They do not have any NFPA rated tags or labels on the boot. Will upgrade the laces. Would love to see the boa system on this boot!

Needs work
Size: 12, Color: Black
I’m disappointed that I spent almost 400$ on a pair of boots and wore them for 3 days and both boot laces broke near the eyelets. As a wildland firefighter I need to be able to rely on my boots.
