Best boots ever. I bought my first pair in the early 90s while in the military and they kept my feet safe, warm, and dry in Alaska and safe, cool, and dry in several desert environments. Kept wearing them daily after getting out of the military. Replaced them in the mid 2000s with the same boot and wore them everyday. Getting ready to buy my third pair now. GORE-TEX waterproof. Thinsulate for insulation. Vibram no slip sole. Goodyear Flex-Welt. All the big names in one boot. Any military person will agree that your feet are an investment and these boots are the best investment. Worn them non-stop for 25+ years. So, if you want a great boot that'll last 12-15 years with no issues. This is it.
