Very cute and comfortable, i wear them on a daily basis.  They are very bouncy, don't make my feet or knees hurt, and I can walk on these for hours.  The only problem I have with them is that they and thus also my feet , get very stinky.  I regularly spray them with lysol disinfectant spray which makes it a tad better.  I do not have this problem with any other flipflops and I also own two pairs of regular cobian bounce sandals.
