One of these days I'm going to drag out the story (again) for those who haven't heard about the time I wore way too high of a heel too early in my high heel journey. I'm not surprised you faded pretty early if 12 cm was your first pair.
People point to the 1980s as being a good time for heels, but looking back through my old photos and watching old music videos, it was and it wasn't. Yeah, elevated heels were much more common back then, but I don't think I actually saw in person anybody wearing what I would call actual high heels. Taller mid heels, for sure, but 4 inch + was just not a thing in real life around here. Not even in college. The heels I thought were so tall at the time just weren't all that high compared to what I wear every day. I actually went shoe shopping with this girl one time, and she bought some black patent leather pumps which were about the highest heels I'd ever seen somebody actually wear. I never got the chance to actually measure them, but I'd estimate them to be right at 4"/10 cm. She wore them somewhat regularly, but then the next year she chose to study in Europe and I never saw her again after that. That is not 100% true, but close enough for this story.
Here is something similar in style and height to what the girl bought when I was with her. As I said, hers were black patent rather than suede.
