I ordered my Toms after reading many reviews - some which said they ran small, some large and the many that said they were true to size.  Mine ran very short.  I think it must depend on where the shoes are made and how the particular manufacturer cuts and puts them together.  When I went to order a size larger they were all sold out except for Navy which i did not want.  I searched the internet and found some at a large prestigious dept store and were a little less expensive with free shipping.  I did notice a week later that Amazon had all sizes and styles available again from a different seller.  One suggestion, if you are not sure and don't mind having to ship one pair back, order the shoe and color you want in both sizes so you will be sure to have them when you need them.  You cannot beat Amazon for customer service.  The return was easy as pie.
