Somehow I managed to end up with one foot a little longer than the other (one is 7.5, the other 8), which forces me to buy the bigger size or have some toes crushed. I was worried that would cause one heel to suffer from the shoe strap sliding up and down, but they didn't do that. They actually feel fine on both feet.  I even wore them with knee-highs hose and the strap on the heel did not slip up and down then either.  They don't have a lot of cushioning, but still comfortable enough for all-day wear.  They also have soft sole so they don't click and clatter everywhere you walk. Recommended -- for dress or casual.
