Nike Comfort 2 Men's Slide Sandals – Black/White/Silver – A slider is actually a kind of footwear distinct from shoes and similar to flip-flops. They are backless and open-toed, primarily an open-toed mule. Usually, all slides are sandals. Thongs and flip flops are usually classified independently. Slides might be high-heeled, flat-heeled or somewhere in between, and could cover nearly the whole foot from ankle to toe, or could possibly have only a couple of narrow straps. They sometimes consist of a single strap or a sequence of straps throughout the toes and the lower half of the foot to carry the shoe to the foot.
