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

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.

Like all Asics I've owned - Good
Size: 12 X-Wide, Color: Steel Grey/Cloud Grey
I've worn Asics for about 35 years now. Every pair I've had, and there have been many, have fit well and gotten the job done. The Gel-Venture 11 are performing as expected which is very well. The cushioning and support in the heel and arch are excellent. Very comfortable to walk and run in these shoes. Finally, and less importantly, the looks are just OK. The cheap "iron on" Asics logo doesn't look good. I've been purchasing Asics for as long as I have strictly for the performance quality anyway.
