I have heard that Salomon and K2 can both be a good place to start with fit issues like yours. It's getting tougher and tougher to avoid boa or some kind of speed lace system these days, though. Nikes use a traditional lace on all their boots, but I'm not sure about the fit on the women's line.
If you're in Alaska, call Boarderline snowboard shop at Nugget Mall in Juneau and ask for Spenser Johnson. He might be able to help you out!
