That is the damn truth. I wear a custom arch support to supplement the bunion surgery I had on both my feet 15 yrs ago. I *HAVE* to wear those things in my tennis shoes, particularly when I train or else my feet start tp ache. But go figure, I can dance all night in my heels. Mind you, they generally need to be a solid heel (not the flimsy little strappy jobs), and I'm good to go. The really funny part, one of my favorite pair of shoes to go dancing in is my 4" hooker jobs.
