Crocs Cayman Shoe for Adults:This was the 2nd pair of Crocs Cayman shoes that I bought on line. The first pair was perfect. This pair was made out of hard rubber and had no give to them at all. They are not able to be worn. Also, I felt the shipping charge was excessive. The first pair of Crocs I ordered were the exact same price and included free shipping. I will not be doing any more business with Amazon, unless you people resolve my complaint to my satisfaction.
