OK, suppose the worst case happens and the pax have to exit via the chutes.
What's the first thing prior to making that leap?
TAKE OFF YOUR SHOES!
..erm, well actually not quite. From my memory of the safety cards, only sharp, pointy shoes need to be removed before goind down the slide.
Unless the kiddies are wearing stilletoes, that shouldn't be an issue.
Ciao for now
