We grew up wearing zories when they were 75 cents at the drug store and we've always called them zories. By the way some people call them flip flops or thongs. The designer's name was Zorie.
I just saw some in a fashion magazine for $80. They had rhinestones. I still like the drug store kind that now cost about $3.99, glue $2.50, rhinestones $4.79, happy feet- priceless.
