hey guys, I need some input to hy my shoes hurt my back heel. i am currently wearing an UK7.5 size. My previous shoe was a cheap leather shoe where the heel is quite soft and with padding. This was a size UK 8 with quite some room to spare. The shoes are new and this is the second day i am wearing my CJ's however everytime when i walk my heel is somewhat rubbing against the heel of my shoe. The heel seems very hard on my CJ's and now I have developed a sore. My foot feels snug in the shoes. Does anyone have this similar problem? What can i do? thanks in advance.
