Got my shoes today! The cobbler did a pretty awesome job. I'm very satisfied. The heel is visibly shorter. When I measured it, it was shortened by only 1cm, but it makes a huge difference!
1) The heel looks much less daunting
2) The balls of my feet don't burn as before. Much more comfortable and I'm more confident in them now.
3) I'll be able to wear these more often and even to dance!
Shortening the heel didn't affect the balance or the shape of the shoe. That's because the cobbler took off only 1cm. So if you have super high heels that are just sitting in the closet, go to the cobbler and ask him if he can shorten it!
