Two Buckle Slide Sandals – A slider is a type of footwear different from shoes and similar to flip-flops. They are backless and open-toed, basically an open-toed mule. Normally, all slides are sandals. Thongs and flip flops are generally categorized independently. Slides can be high-heeled, flat-heeled or somewhere in between, and could cover approximately the entire foot from ankle to toe, or could have only a couple of narrow straps. They sometimes consist of a single strap or possibly a sequence of straps across the toes and the lower half of the foot to carry the shoe to the foot.
