My kids complain, but I have to insist they wear watershoes(aquasocks or sandals) near pools and at waterparks. Three months after a trip to WDW, my son had surgery to remove painful plantar's warts on the bottom of his feet. Although we are not sure where/when he picked up the virus, it was likely by the pool at the resort. For three months the podiatrist treated them, and finally had to remove them surgically(painful and expensive). Fashionable or not, I prefer to be safe rather than sorry.
