Sailor Venus

Minako Aino/Sailor Venus/Sailor V is one of the inner Sailor Guardians in Sailor Moon.

Footwear
Minako Aino wears black mary janes in her daily school life. When she transforms into Sailor Venus, her mary janes disappear and the orange single-strapped pumps are on her feet. These pumps look very similar to the mary janes in her civilian form, but is ankle-strapped unlike the mary janes.

Her transformation was undone once in the SuperS Movie, but she was stuck in the mid-transformation state then, so she didn't show her shoes during detransformation. But there seems to be official picture of her shoes turning to ribbons and forming half-transformation boots. It would be a detransformation from her super sailor form.
