Merlin- you know what, I was bought the Orcas for the exact same reason, they were cheap. I used them once, just enough that I couldn't return them, and I really didn't like them. They are simply too stiff. They are the only Pinnacle Product that I have been disappointed with. There is another option, although I am not sure if you will like it. Take the Orca boot and some 60grit sandpaper/angle grinder and/or a razor blade. I have modified/reduced the sole on the Orca and you can make it small enough to get into the XXL. Since you got them so cheap it may be a good option. Also the Pinnacle stuff runs true to size, so they say 14 they mean it.
Or you can hopefully exchange them for this boot
6mm Merino Medium Sole
this is the warmest wet boot that I know of.. the merino is fantastic, warm, and it doesn't smell
You can try the 3XL w/insteps to size them down some, but I will say, I put my foot in them with a running shoe on and they were still too big. I have a pair of wader like rubber boots that work with it nicely. I am not sure that you can make the 3XL pocket small enough to work
