Okay, from what you've said so far, I can already tell you that you're a big boy who's gonna need a big board. With size 15 feet you're going to want a wide board for sure, for example the Forum Bully. (That's the wide version of the board I ride.) At 220 pounds, you'll likely want something that's 158 or longer, depending on what you want to do.
Which leads to my point - to give you a good recommendation, we'll need to know what your intention is, are you looking for an all mountain board? A park board? A freeriding board?
