I've been dancing for about 18 months and my husband and I are progressing into silver. From my perspective I agree with the advice about the lower shoes. You're having a problem (not a doc, just worked in healthcare for over 30 years) with that foot because of the pressure on the nerves. Absolutely find a comfortable shoe. The problem is locating one! In Wisconsin, it's almost impossible to find anyone who has a wide variety of shoes.
I've tried about 20 pairs of shoes before I find one that fits and is comfortable. But as they say, they do stretch out, so now I've gone a half size down. For me, 2 to 2 1/2" heels work, but I'm used to that height. Keep asking local dancers who they use or where they purchase shoes. I did find one Supadance which was perfect, but couldn't see spending that much money. But I've tried on $180 shoes that didn't work as well as a $95 Very Fine brand. Luckily, we have a woman who sells from her house and has a huge supply so we can try them on and order from her.
I hope you're still dancing and have found the right shoe. It makes all the difference for me.
