Add further support to your pointe shoes by adding an elastic ring around the shank housing. This wide elastic helps prevent twisting, pushing too far over the box and brings the shank to the underside of the foot. Feel the difference!
These elastic rings are nice as long as you get the right size! You don't want it to be too tight or too loose. I have tried wearing these either inside the shoe or around the outside. Both options are useful in their own way.
