Never had a problem, but i have always worn leather soled shoes for dancing, although the missus is talc crazy, before we went out with one another Sandi and i went to Pritchards "do" at Dudley, where talc was banned, she filled an ash tray and put it under the table, to dip her shoes in before dancing, and was most indignant when the management removed it, having followed the white footprints from the dancefloor to beneath our table!!!!!!
Gotta say if i wa still promoting as a trained IOSH health and safety rep., first aider and trained risk assesor, i would be carrying out risk asessments and would as a result ban talc, and also those ridiculously outdated and totally "cringeworthy" accrobatics during dancing at any event as they are a claim just waiting to happen, all that throwing yourself about was ok in '74 when we were kids, 50+, people doing it now look silly i'm afraid, we may as well just come out and dance the charleston, another silly outmoded/outdated dance form!!!!
