I'll raise my hand.I don't have an answer though.
When I put in a real hard week, like one I did the middle of last August (275 miles with ~23,000' gain) the outside ball of my toes will be in major distress.
I've tried different shoes and socks, added some shims to hopefully make me pedal more on the large toe ball and moved my cleats to the furthest inboard position I can.
Once off the bike and a little rub on the feet the pain goes away.
When someone has an answer I'd love to hear it.
