This is an appendix to the article that was published before on How to Sew Ribbons on Your Pointe Shoes, answering a question from a reader. (https://kodamaballet.wordpress.com/2013/09/11/how-to-sew-ribbons-on-your-pointe-shoes/)
This article explains a little further on the following:
“An alternative is to sew a very short loop of elastic just long enough to reach from the heel seam of the shoes to the back of the ankle (behind the Achilles tendon) and thread the ribbon through it as you wrap it around your ankles. The heels are pulled up by the ribbons around your ankles and you do not have to risk the discomfort of having elastic around your ankle as well as the ribbons.”
As in the photograph on the right, sew a piece of elastic (use a fairly strong piece of elastic for this), which is twice the length from the edge of the heel of your pointe shoes to the back of your ankle, in a loop. One could either sew two ends together or sew them very closely next to each other.
Through this small loop of elastic, thread the first ribbon (always wrap the inside ribbon first. This helps keep the pointe shoes stay with your feet) and wrap it around your ankle. It is not necessary to thread the other ribbon. Just wrap the ribbons around your ankle as usual and tie them, and off you go dancing.
I have been using this method for a while. It was nice not to have both ribbons and elastic around my ankles. After that, I found such well fitted shoes that did not need any elastic to keep the shoes on my heels. So the elastic was made redundant.
