I have these, and I love them dearly.  Very comfortable once they're broken in (don't plan to wear them all day for the first couple of weeks!).  I bought them as motorcycle boots, and they were perfect for that purpose.

HOWEVER, the zipper on one broke after only about 4 months of wear.  Apparently Doc Martens doesn't have a lifetime warranty like they used to, and I'm having trouble finding a local cobbler who will replace the zipper.

So while they were good while they lasted, I bought them based on the "indestructible" Doc Martens reputation, and was disappointed.  I've had $30 Wal-Mart boots last longer.

They also fit about a half-size too large, but that's easily fixed by wearing thicker socks.
