I've been fighting the same symptoms for a year with some success. For me the most effective solutions have been new shoes and move the cleats as far back as possible. I also try to remember to move my feet/toes around while riding to increase circulation and unpinch nerves. My shoes are pretty loose...

I've never been a high heel ot fashion shoe type woman, but I've spent a lot of time on my feet.

Metatarsal buttons didn't help...

Good luck with finding a solution. The pain gets in the way of the fun.
