I've had these boots for 3 years, and liked them for the most part. Great traction, good in warm weather and temps down to about 25F. And after getting a pair of aftermarket insoles they've been fairly comfortable. Still I definitely need to be conscious of any hot-spots on a long hike. However on a recent backpacking trip into the Sierras the heel of one of the soles started to separate from the boot. This is a boot with 140-180 miles on it. So while not a bad boot, I'll be considering other options for a replacement.
