Beautiful shoes, ordered two different sizes to see which would work for me after reading reviews.  One size definitely too big; the other fit perfectly except........it slipped off the heel and slid of my foot.  Now I am thinking okay I will just put a heel grip in the heel.  Nope the shoe would not cooperate: slip and slide again.  Now again.  I am definitely thinking I am going to make these shoes work for me.  So I put in those nice foot petals and guess what:  slip and slide again, again.  Now again, again I am going to outsmart this shoe, so I eliminated the hose and used bare foot.  Aha.  it did not work:  slip and slide again again.  Now, the shoe won, I sent them all back after it "flopping" off my heel and almost causing me to tumble. I called Cole Haan and talked to a nice gentleman, he admitted, somewhat, that people were having problems with the heel of this shoe.  Someone honest for a change.  He also informed that this shoe is the Nike air technology, but Cole Haan will not be using Nike in the future as they have made arrangement in a different direction.  I hope that direction is aimed at the heels,  Since these shoes are not made in Italy, I think I am definitely going to not buy them and stick with my Aquatalia that I buy from AMAZON as they seem to have the best prices.
