The first pair's soles just crumbled into nothing within a few weeks, while the second pair had pretty severe separation occur in the sole after a few weeks. Both were used pairs, not sure how old by the time I picked them up.
Like I said, both of my Timberlands were the "earth keeper" variety. Those are known to have issues with sole longevity, and some people report separation. But I wore each pair for about 2 years and it was only really towards the end that I had the soles really degrade to worthless.
Side note, I'm cheap as fuck so I'd say that by 1.5 years the boots showed heavy tread wear, by the 2+ year mark, the heel had holes worn into it that exposed the air cushion. Though even by that point they were still comfy as fuck, and the leather on top looked fine. I could've replaced the soles and gone for many more years, but I opted to replace the boot instead.
