Never danced in my shoes always kicked them off before I went onto the dance floor just loved the woolly Bully.
The only time I ever left my shoes on was many years later ( I struggled to finish the dance lol ) and one of my shoes flew off and skidded across a table knocking a glass of beer off the end

Luckily I knew the chap whoes beer it had been - still pee myself when I think of that incident
Can't say I know the name of your friend maybe she has a double lurking around
