Merrell Lilyfern Slide Sandals – A slider is actually a form of footwear different from shoes and just like flip-flops. They’re backless and open-toed, primarily an open-toed mule. Usually, all slides are sandals. Thongs and flip flops are normally classified separately. Slides might be high-heeled, flat-heeled or somewhere between, and may cover nearly the whole foot from ankle to toe, or might have only a couple of narrow straps. They usually consist of a single strap or maybe a sequence of straps across the toes and the lower half of the foot to hold the shoe on the foot.
