These are the best boots I've ever owned.  They're warm, practically impervious to snow and water, have great tread and are easy to break-in.  They are a bit on the heavy side, but for the durability, it's worth a little extra heft.  I'm a delivery driver in the Northeast and have dropped dozens of heavy bags on myself, had doors slam shut on my toes, and have trudged through snow up to my calves to get to customers in snowstorms.  These are now all I'll wear to work in the winter!
