John, I also dive and bike. If I have been doing a lot more biking than diving (especially mtb'ing) I find that my feet/ankles can use some stretching out as it seems to tighten everything up in that area. I can usually feel the tightness when I point my foot fully, letting me know it needs some stretching out. I now try to get in some stretching and yoga on a weekly basis to keep the problem away(and to keep this old bod flexible). Don't know if this is kinda the same thing you are experiencing or not. It has never caused me pain, just some tightness. You might also want to look in to your bike setup, make sure everything is lining up properly. An alignment problem on your bike could be causing stressed to your ankles that only show up (or show up most) when you are diving. Hope you figure it out.
And it looks like you've already got the message to lay off that poaching. So happy diving to you.
