Does one necessarily has to suffer to look good?
Maybe sometimes things are bigger in reality than in ones own wishful thinking and it may result in sore spots.
You can change your nice purple shoes or try to shrink your feet.
The shrinking option might be difficult and not very promising and you really don't want to put off your brand new princess shoes.
So what to do?
If all else fails one can walk around with patches on the heels. Probably it hurts and doesn't look very princess-like but you can feel like you have beaten reality.
I guess reality pity you and lets you life your princess-patch-thing without further notice.
It's up to you to cope with it.
