In 12 weeks I am already getting ready to send back my second pair.  These are by far the most comfortable boots I have ever worn, however the quality is terrible.  The soles split away from both pairs in the matter of days.  I will admit I am very tough on boots but these are WORK boots not casual boots.  As others have said, they are very heavy and that should be taken into consideration if you do a lot of walking like me.  These boots are also not for wet conditions.  They do not claim to be waterproof so I did not expect to stand in water and stay dry, but my feet have gotten wet from walking through puddles and even across wet lawns.  I will say I have never had a problem with the customer service in getting any of my Timberland boots replaced under warranty, although paying to ship boots back for the same problem gets old and expensive.  And to top it off they are made in china....
