I've had two of these boots in the last 5 years.  I am a full time landscaper during the spring, summer, and fall, and do snow removal and construction the rest of the year.  I am on my feet constantly and these do not let me down!  I've had to buy insoles for each pair after about a year, but the rest of the boot holds up nicely.  The insulation is great even in the cold New England winters.
