This is it. Who thought riding a bike could be done so wrong for so long? My pedal stroke is in rehab right now, and it is not an overnight thing - you really have to focus.

FWIW, I started a foot discomfort thread a while back and have updated it from time to time. The latest remedy that has worked the best, better than anything else I have tried in 20 years, is toe separators. They cost about $8.00 at Walgreens or drugstore.com, and I sleep with them. This allows my foot to relax in a normal, i.e. un-cramped position. Not an overnight thing, but again, more like a rehabilitation for a foot that has been abused for so long.

For reference.
