Perhaps it would be useful to eliminate a suspect by switching back to the old shoes, or to yet again different shoes?

Maybe the new shoes have some chemical or fibers in them that irritates your foot. Maybe the roomier shoes are letting your foot spread out, and the resulting tissue growth is itching.
