These embellished things that I'm not sure even qualify as human shoes:
Some of the socks were open toe.
Some pairs had a less extreme platform.
Some shoes were shockingly flat.
Some minimalist outfits kept the focus on the accessories.
Also of note: stilettos are getting obese.
Prada showed platforms that got knocked off everywhere a few seasons ago.
Prada has also shown socks and sandals before.
So maybe these crazy leather socks were just meant to keep everyone from slipping right out of their heels.
