Adidas Men's Adissage Sc Slide Sandal Size 11 – A slider is actually a form of footwear different from shoes and comparable to flip-flops. They’re backless and open-toed, primarily an open-toed mule. Usually, all slides are sandals. Thongs and flip flops are usually labeled independently. Slides might be high-heeled, flat-heeled or somewhere in between, and may cover nearly the whole foot from ankle to toe, or could have only one or two narrow straps. They usually consist of a single strap or maybe a sequence of straps through the toes and the lower half of the foot to hold the shoe to the foot.
