What is the best way to break in new pointe shoes?

Press as hard as you can on the shank of the pointe shoe when you have taken then off and set it on it' toes so it would be like sitting the shoe on pointe and bending it backward/forwards and try pressing the box of the pointe shoe so that is flexable also , you can also ( if you have hardwood or cement flooring ) slam the end of the pointe shoe on the ground. Or stick your shoe between a door and the wall and close the door to it's farthest with the pointe shoe in between and bend the shank. You can also take sand paper or scissors and use the side of the scissors or the sand paper and brush the ball of the shank to make it have more grip . :) hope this helped :)
