Be sure to keep in mind that, as far as mens' shoes go, your Dr. Marten size is one less than your regular shoe size.
The shoes are great quality. To break them in, I took them for a spin on the treadmill. They felt comfortable even while running.
EDIT: Under a year after purchasing them, the sides of each boot started to crack significantly. Not deep enough for water to leak through yet, but the cracks are deep and numerous. I've no clue if this is typical of Doc Martens (I understand that they have moved production to Asia), or if I received a defective pair.
