After reading all the glowing reviews which say how utterly comfy these are, my hopes were very high.  And truly the foam material is comforting to my feet, including my left foot which has been experiencing plantar fasciitis symptoms of late.  What keeps these slides from being great, in my opinion, is the severe amount of rocker built into the sole.  They force me to balance myself from front to back while standing, and I mean they make me expend some effort.  They make me feel like I'm teetering back and forth, unsteady.  Walking in them is okay because the rocker helps propel me along, but standing still in these is a nuisance.  Maybe a younger person (I'm 59) wouldn't be bothered so much by this, I'm not sure.  Frankly, I don't see what the hoopla is about; I have some Crocs clogs that I think are more comfy to stand in or move about slowly, although they tend to flop around some on my feet and that is why I wanted to try some slides.  Oh well, I'll keep these for now.  Note: I did not buy these through Amazon but I hope my review is helpful to some.
