I ordered woman's size 11 which is my usual size and my toe hit the end of the shoe.  I've worn this same shoe and style before and don't remember a problem with size 11.  So I returned them and got a size women's 12.  The 12 is very roomy and I must wear socks to help them fit better but because of the larger size I am able to add orthotics.  With added gel support and socks these shoes are very comfy.
