New black strappy sandals for going dancing on forthcoming holiday. I will be in them hours.... I will be wearing them round the house but how can I make sure I will survive? The soles are slippy (not good combo for dancing) is it sandpaper you use on the bottoms? And do those squishy insert things stay in sandals? The ones that are meant to help the ball of the feet? I'd worry they will show or start slipping!!
