Which Pigalle are you referring to?
Pigalle 120 and Pigalle Follies (all heel heights) seem to be discontinued, or perhaps replaced by Hot Chick. Hot Chick is the shoe I was directed to when searching for Pigalle 120 and Pigalle Follies.
Pigalle 100 and 85 are still available at the Louboutin website as of today.
Maybe one of insiders here can weigh in on this.
Miss Z looks to be a similar shoe construction as Apostrophe, perhaps with a slightly longer toe box, but it's hard to tell from pictures only. I can't say if Miss Z is comfortable, as I don't own a pair. I only know about Apostrophe 85, which has a very narrow toe box and will be comfortable, especially in suede, if you have narrow to medium wide feet.
