I wanted to know if slippers and slides mean the same thing, so I did a search and the following is what I found. It doesn't really say if they are one and the same.
Are slides and slippers the same thing?
A slide, also known as a slide sandal, is a backless, open-toed shoe that gets its name from being easy to slide on and off the foot. ... The slide is a type of sandal, but not all sandals are slides. For example, flip flops might be easy to slip on, but they aren't slides.
