I just got these and I am amazed.  I thought I was nuts to spend this much on a plastic sandal.  But I have worn standard Fit Flop sandals and they really help cusion my hips and legs, which are generally painful due to arthritis.  I find FF's are the only shoe that is more comfortable than no shoe at all, and most shoes, even sandals, are not comfortable for me.  So I tried these and I am glad I did.  They provide the FF cushioning without the flapping sound, so they will be better for work.  They also have some additional wobble board technology per the sticker on the bottom.  They are attractive and a good fit (I wear a 7.5 and got a 7).  They have a velcro strap around the back of the heel which keeps them firmly but comfortably on your feet...no slipping around.  The only thing bad about these shoes is that I have so many other shoes that will never get worn again.
