slides
Slides or sliders are a type of light shoe that are characterized by having a loose heel that holds on to the foot from the front. Like flip-flops, they are typically employed in casual situations, in addition to being a unisex footwear worn by both sexes. Sliders are distinguished from flip-flops by their vamp strap which does not separate the big toe from the rest of the toes. (From Wikipedia)
Compared to slippers which are indoors, slides are often used outdoors.
