J Crew Leopard Slide Sandals – A slider is actually a form of footwear different from shoes and just like flip-flops. They are backless and open-toed, basically an open-toed mule. Normally, all slides are sandals. Thongs and flip flops are usually classified individually. Slides can be high-heeled, flat-heeled or somewhere in between, and may cover around the whole foot from ankle to toe, or may have only a few narrow straps. They usually consist of a single strap or a sequence of straps through the toes and the lower half of the foot to hold the shoe on the foot.
