First thing's first: this product listing is inaccurate.  The listing claims these boots are Titan safety-toe equipped and only weigh 1lb each.  In actuality, these are steel-toe boots that weigh over 2lbs each.  Unfortunate, since I was looking for a lighter weight boot now that I'm not really working in an environment that requires steel toe boots.  After doing some research, Timberland apparently doesn't make this style of boot in a composite safety-toe version.  They do have a soft-toe, but that's listed as Timberland #89631.

Had I not returned them this would have been my second pair of these boots.  The first pair were great and stood up to a moderate amount of abuse for about a year and a half.  They were very comfortable compared to the last set of Timberlands I had, thanks to the cushioned mid-sole.  Eventually the insoles burned out, and the synthetic ankle cushion started pulling away from the leather on of the boots.  Not really a design flaw, just something that's eventually going to happen to any boot with that kind of design at this price range.

I did not have any problems with the soles on these boots, as others seem to have.  Grip is great, and they really do grip better on slippery surfaces (ie. oil on linoleum) than any of my sneakers.  No, they're not waterproof, but I've never had a problem with my feet getting wet, even when tromping through mud and snow.

As others have mentioned, they are heavy.  They use a steel toe and have some sort of flexible steel puncture-resistant plate under the mid-sole, which add up to make one heavy boot.  But they're still super comfortable and were durable enough for me.
