I'm not even sure what they are
I know she has awkward feet so we went to a push shop to get some non school shoes ( wide foot very high instep)
Oh she HAS got a high instep said the assistant. She can't wear flat shoes without a strap and she rolls her foot.
She said she might not need them especially as she is doing lots if foot strengthening excercises at ballet.
Where do you get them from? How much do they cost? What do they do?
