Recently I have become aware of the existence of these arch enhancing prosthetic pads that fit over the top of the foot to give the appearance of a more arched foot. The reason I ask is that I have noticed a particular dancer whose foot seems to have become much more arched when you compare her older vs newer videos on YouTube. Now I am not a dancer, just a lifelong ballet fan, so I’m in no way qualified to make a judgment, but if true, this seems like cheating to me. The questions I have for those of you more in the know are, how widespread is the use of these devices, do professional dancers actually use them, and if not can a dancer’s arch change to become more arched naturally as he/she matures over the course of their career?
