hello! Thank you for your question <3
okay, if its a brand new pair of pointe shoes, you might want to make sure these are fitted correctly to your feet so maybe ask a dance teacher or a qualified shoe fitter from the dance store to check that the style you have its correct for your feet :)
If its an old pair, maybe they are warn out and you need to buy a new pair :)
Also make sure that your ribbons and elastics are sewn correctly and are tight enough and sewn in the right place. Make sure your draw string on your shoe is pulled in tight to make the back of your shoe tight enough to stay on your heel :)
Some styles of pointe shoes are made with a low heel, so maybe look for styles that come up higher at the back.
Hope these helps you, keep dancing and if you have anymore questions please feel free to ask! <3
Oh thank you so much, means a lot <3
