There are countless good things that come from Maine, like tapas, and the Gasol brothers, and, wait, you said Spain, right? OK good, because that place is awesome. For good things for your feet that actually do come from The Pine Tree State, Yuketen.
Just dropping at the Field House, Yuketen's traditional workwear inspired boots/oxfords are modeled on "traditional artifacts of the rugged and refined American past", and made from super-durable raw materials like their exclusive all-vegetable tanned leather, and American naked leather that's "thick but soft", which isn't quite the consolation you may think it is.
Boot options include the designed-to-protect-you-from-bites Snake in brown leather with an adjustable shaft and true moccasin-style construction; the sturdy veggie-tanned Maine Guide with a white Vibram Christy sole that provides ankle support via a wide/soft footbed; and a moccasin-toed camp-style boot in Scotch grain with an adjustable midfoot strap called the Dress Ranger (Hi ho Silver a-YAYYYY!!!).
Not-boots range from the aforementioned Oxfords (the straight-tipped Milspec with a Goodyear welt), to accessories (the leather/brass Studs belt, Cordovan leather money/business card holders) to bags like the single pocket wool Triangle backpack, and a buckle flap messenger in leather, wool, or herringbone called the Mail Man, which is a slam dunk for you, assuming they can keep 'em in Stock(ton).
Because work sucks, there's also less rugged footwear like the self explanatory Brass Studs Loafer, and a cordovan leather Penny Loafer in colors that include Crazy and Whiskey, the latter of which might make you enough of the former not to notice rainfall is concentrated along the coast and in inland mountainous regi...oh, right! It falls mostly on the plain, sorry!
