I think that another reviewer might have said that these shoes were a bit stiff in the heel area and I also found that to be true.  I wore these on a short walk without socks and came home with a sore spot on one heel.  I think that they will gradually "wear in" but I would recommend wearing a thin sock during the initial wearings.  That said, they really are cute and are a color I need.  I also own the Keen "Sienna" shoe in another color and never had any issue with heel discomfort.  About Keen in general, my experience has been great---comfortable shoes that look good for a long time.  If I never get this Summer Golden pair broken in, I'll write again.
