I wanted a pair of shoes that I could easily slip on and off for taking out my dogs or running a quick errand.  While walking down a set of stairs, the soles slipped/stopped on a stair and since the entire shoe is made of mesh, my foot slid forward and I fell down the stairs.  I will still use them just to run the dogs out, but I would be very careful when wearing them in public.  Watch the type of surface on which you are walking.
