Nike Women's Comfort Slide Sandals – A slider is a form of footwear different from shoes and just like flip-flops. They are backless and open-toed, primarily an open-toed mule. Usually, all slides are sandals. Thongs and flip flops are usually categorized independently. Slides could be high-heeled, flat-heeled or somewhere between, and could cover approximately the entire foot from ankle to toe, or might have only a couple of narrow straps. They sometimes consist of a single strap or perhaps a sequence of straps over the toes and the lower half of the foot to hold the shoe within the foot.
