I love Amelie and I love these shoes! I am uber-jealous. Does the Sharpie hold up well? Did you seal the shoes somehow?
I havent worn them out of the house yet but i think the sharpie will be ok. a few months ago i wrote my name on the bottom of those same shoes and it didnt wear off, so I didnt think sealing them would be necesary. it'd probably be a good idea just incase anyways.
