don't just get "insoles". Get some metatarsal pads. And lower your heel height.

How often have you been practicing? I must admit I have some doubts about your school if you "just graduated to Bronze" after just over a month. While it might be possible, I don't see how you could be a Bronze level dance even if you managed to put in 40 hours of practice a week for a month. So part of my concern is that your studio is substituting quantity for quality: they are teaching you lots and lots of moves 'cause it's fun and generates money, but your body is not ready for those more advanced moves yet.
