I purchased these because my podiatrist suggested I buy a shoe with rocker soles.  The reviews here were good so I went for them.  I'm an 8 1/2  but since warnings were given that they run small, I bought the 9 instead.  Plus, they came in W (EE), which is indispensable for me.  Bingo! Perfect fit.  Man, I love them.  My feet have plenty of room.  They rank with the best shoes I've had and I'm 58.
