Stilly's Pigalle Parade Plus!!!

Love the way your feet fit these heels. No toe gap. No heel gap. Perfect. Do you buy your usual size or size down? I usually need to size down .5 or a full size to get the snugness I need so the heels won't slide off my heel when I walk or stand for a few hours.
 
Thanks Christina! With Pigalles it was trial and error for me. I go down a half size on the old style Pigalles like this pair. I actually own Pigalles from a full size up to a full size down. I can go down up to a full size on the Pythons since they stretch more.
