Here are some pictures (sorry, they're not great pics) of the only pair of 379X boots I have. They were brand new, taken the day I bought them so no wear on them at all. Hopefully they can help you make a decision. I may not be a good judge of comparing Alden lasts but from a fit/feel perspective, I don't find it that different from the Barrie last, except maybe a bit more room in the toe box. It's also got more arch support than the Barrie.
Definitely more work boot oriented. Good luck.
