I'm little skeptical of how long this boot will last. After only 40 miles, the sole is starting to delaminate from the boot and if I try to get the boots decently tight the rings for the laces at the ankle pop out. I'm a sawyer on a hotshot firefighting crew and originally I bought these as a possible replacement to my Lowa's since the Glaciers are "WLF boots." It seems weird they label them WLF then proceed to say they're not meant for frontline firefighting or being exposed to heat. If you have anything to do with wildland fire, I'd recommend avoiding these boots. Pros: The boot is comfortable and it does feel good after long sidehills or steep downhills. I also like the adjustable tongue. I can adjust it to put even pressure on the top of my foot which adds to the comfort level in steep descents. Overall it seems to be a decent boot for the price, just not a boot I'd ever use for work.
