I had first purchased the Clark CloudStepper sandals/flip-flops at the mall... and love them so very very much, that I want all my shoes to have this magical cushioning.  These CloudSteppers do have that same cushioning, however, it's not as thick of a sole, so it doesn't feel exactly the same.  I wear these to work, and I'm an ER nurse who rarely sits, and these feel pretty good and keep up.  They also fit perfectly.  I just wish the soles were about double the thickness.
