I had to pass this along and if it's already well known then just ignore me. I haven't danced in about 6 or more years.
I came across a dancer the other night at the new club I'm *trying* to waitress at.
She was talking about these new shoes she had bought. They were the platform close-to-9-inch heels open toed white shoes. Very nice. I asked her that since they were new, didn't her feet hurt?
Apparently where the shoe covered her feet she put duct tape around her foot extending maybe 1/8 of an inch past where the top of the shoe covered her foot (if that made any sense). She also taped her big toe with a small strip and then her last two toes. You could not see the tape at all even when standing there in front of her feet on stage. Apparently this keeps your shoes from rubbing against your feet and causing blisters.
I imagine if you have clear shoes you can't use the silver tape, buy packing clear tape...but anyways, it was a pretty nifty idea. She said she never gets blisters this way because the shoes never rub against her skin.
Just an idea to pass along.
