I'm assuming that is a typo you are looking for pedals in your size.. I believe you mean shoes. Size 15 I believe comes out to 50 metric, The Sidi genius come in that size, seen them for sale before.. might have to special order them though. Why not talk to your LBS and see what they can get in your size, then it is easy to return if don't fit. Shoes are a very personal item, one I like you might not like, and some are wider then others etc...
