What can you do when your heel keeps slipping out of the back of a shoe? - heel coming out of my shoe

My mother only bought these wedges and peep toe are a little too big ... the smallest size is too small if I did with those who were a little bigger to go to ... The only problem is that when it comes on the heel of them ... The material is canvas and the work is a kind of hemp, and as I said the stains are to have a certain level, to whatever they use / do to prevent the shoe on?
