Yes flip flops used to be called "thongs" when I was young also.  I recall my mother saying once upon a time "thong underwear, what is that? thongs are flip flops" So there you go.
As far as "toning shoes" go... If it seems too good to be true...

well I bought some yesterday and they are soooo comfy! I thought I would wear theses when I go to Disney the end of August. I thought each day I will wear them so I can break them in before the trip. I got them at Rogan's shoes for 42.00. They have a deal buy one get the 2nd pair 50% off,I only had the fit flops so she gave me 20% off. I got the Brown ones. They are not the cutest but when I have them on they actually look quite nice!
 

On my recent trip to FL, I found a pair of Fit Flops at Ross for $24. LOVE them!! They are SOOOOO comfortable!!! I wish it was warm enough to wear them out and about, but I do wear them around the house. Unlike regular flip flops which have very little support and make my feet hurt because of no heel, these are structured to include great support and I'm really glad I bought a pair. (I didn't find any workouts while I was there, but just this purchase alone was worth going)!!

Thanks, girls, for posting this thread!!  :) ~~MRS~~
