Sports orthotics, crafted from multiple layers of different density foams are often the best choice for active people. These inserts provide 'just enough' support while allowing movement in the correct alignment to develop strength. It is best if these inserts are custom made, so you may need to hunt around in your local area to find a podiatrist or physical therapist who makes them.
As the strength in the foot and the rest of the body develops, the amount of support that the orthotic is giving can be reduced, so that it is more of a ‘reminder’ (Proprioceptive feedback) to stay in the right place.
Many people have tried to create an orthotic device that can be worn in ballet shoes, but unfortunately, I have not yet seen one that is very effective. My feeling is that dancers should be able to control the position of their feet without support in their dance shoes, and this is a definite requirement before starting en pointe.
I do however also recommend that students dancing full time have a soft supportive insole in their day-to-day shoes. When our feet have been working so hard all day, they do need a little support to prevent any overuse injuries. For this, I recommend a heat mouldable insert that simply helps support the muscles of the foot, rather than structurally repositioning the foot. Obviously, this needs to be accompanied by a good supportive shoe for the best results!
Unfortunately, sloppy ballet flats just don’t cut it!
We do have these heat mouldable inserts available in our Online Shopping Cart and they come with clear instructions on how to use them.
Please also remember that inserts may be used not only for people who pronate (roll in) but also for the ones who supinate (roll out). This can be a bigger problem than many teachers realise. Some students, in their attempts not to roll in, try to correct the placement of the foot by rolling out. Unfortunately, this can actually block mobility of the foot and lead to other issues.
I do hope that this has answered your question well enough!
