I had a pair of these boots that lasted 7 1/2 years, and just bought a new pair.  They feel like a dream on my feet, no break in period, and I know from experience that they will last.  My other ones were STILL GOOD, however the tread was very worn on them, and instead of having them resoled, I decided to buy new ones.  You cant go wrong with these boots, as I am a police officer in NW PA, where we see very brutal weather in which I have NEVER had a wet foot, and very seldom do my feet get cold.  I work out in the field, NOT behind a desk, and although they are pricey, they are made in America and will certainly last.
