Thought I'd post an update. The shop down in Jacksonville called me Saturday to tell me the size 46 Lake CX238's that they ordered for me came in. Couldn't get free to drive down there until yesterday. Oh. My. God.!!! My messed up right foot slid easily into the shoe, and when I clinched up the BOA buckles, the shoe cradled my foot like a slipper. The left shoe was still narrow enough that it could be tightened into a very secure anf comfortable fit on my "normal" foot. I have never ever had a pair of cycling shoes fit me so comfortably right out of the box. Needless to say, those puppies came home with me. Still have to mount cleats on them, but the plan is to take them for a good long ride today. Meantime, thank y'all for your input. It's helped me find what seems to be the solution to keeping my odd-ball feet happy on the bike.
