I live in snowy and icy Michigan, often working in outside conditions.  I've been buying Timberland exclusively for years and they have treated me well.  However, a month after buying them, I have a few problems with the Earthkeepers.  First of all, the tongue on EACH boot is the victim of a poor stitching job, causing the top part of each tongue to be sewed only halfway.  Once tied, this is no big deal, but a bit disappointing considering the price.  I called for an exchange, but apparently I have a rare (or very common) foot size and was able to only return for a refund or keep the boots as I bought the last pair in my size (13W).  I decided to cut my losses and keep them.

One other manufacturing problem is that it appears as if the sole on one of the boots is starting to come unattached to the boot itself, toward the heel end.  I would be surprised if these boots lasted even a year before needing to getting resoled, not due to the sole wearing down but because of the sole actually coming off.  For now the sole is staying on and does not appear to be loosening any further but I am wary.

Speaking of the sole, the traction of the boots is pretty bad.  If you work in any sort of environment with slick floors be prepared to find things to hold onto so you don't slip and fall.  This was not a problem with other Timberlands.  I'm guessing it has to do with the "earth-friendly" material.

These boots, however, are certainly not all bad.  The fit is great.  After a short break-in period of maybe a week I am able to wear them for 12 hours without my feet getting sore.  The arch supports felt a bit obstructive at first but now have conformed to my feet.  They look great, as well.  Not totally water-proof but as long as you are not splashing in puddles your socks should remain dry.  All in all, not perfect, pretty good, but not as great as I would be hoping for from Timberland.
