I have had these shoes for less than a week and have only run in them twice, so this review may be premature, but I am very impressed with these shoes.  They look and feel great.  I bought these because I wanted a minimalist feel but I didn't want to buy toe shoes.  I have medium to high arches, but I have not noticed an issue with support; however, I did half of my run in these shoes before switching back to my regular running shoes, and I did experience some aching in my arches.  The aching only lasted about 1 min and it went away when my feet got used to my old shoes again.  I also wear these shoes to the gym where I use the elliptical machine and do some light weightlifting.  They were great both, and as of now, I have no complaints.  Even if they don't work out as actual running/exercise shoes, I would still be happy to wear these around casually because they're cute and comfortable.
