Double Buckle Slide Sandal – A slider is a form of footwear distinct from shoes and just like flip-flops. They’re backless and open-toed, basically an open-toed mule. Usually, all slides are sandals. Thongs and flip flops are normally classified individually. Slides could be high-heeled, flat-heeled or somewhere in between, and could cover around the whole foot from ankle to toe, or could have only a couple of narrow straps. They sometimes consist of a single strap or perhaps a sequence of straps across the toes and the lower half of the foot to hold the shoe on the foot.
