Need help dating black Ferragamo slingbacks!

[Agnes Carol]

Hi all! I need some help dating two pairs of Ferragamo sling backs. I was thinking 80's but some things I read online had me thinking maybe 70's instead. Thank you!!!

I think that they are early 80s.

The pair with the cap toe actually looks like 1990s to me, but the satin pair looks like early 1980s.
