Have you ever been to a big theater ballet production and notice that the ballerinas appear to be dancing in shoes secured only by satin ribbon, and they also appear to have not the slightest worry about their shoes slipping off? The truth is they are wearing the Gynor Minden Invisible Elastic, stretchy, lace-like material that virtually disappears next to tights. Comes with an ample amount (30" long) for two pairs made with imported European Invisible Pink Elastic, works for technique slippers, too.
My daughter wasn’t a fan of this elastic at all. She found it to be very weak and not supportive at all. We switched to the Bloch Covert elastic and found that worked much better.
