I have a size 15 foot and am tall and thin (6'2" 165lbs). Got a pair of Orvis Silver Label waders (the yellowish ones) in size XL/Long. Sizing chart shows bootie as 12-14. Matched with their Henry's Fork felt boots in 15. They are working OK. Would prefer a tiny bit more room, but they have been working OK for me for 2 years. My foot is on the narrow side (measures B I think), which may help.

By the way, they are a little baggy, but not so its a problem. I think I tried on a Simms XXL at a shop at the time, and could put 2 or 3 of me in there, but no feet.
