Nike Men's Benassi Solarsoft Slide 2 Sandals – Grey/Black – A slider is a kind of footwear distinct from shoes and similar to flip-flops. They’re backless and open-toed, basically an open-toed mule. Generally, all slides are sandals. Thongs and flip flops are commonly categorized individually. Slides can be high-heeled, flat-heeled or somewhere in between, and could cover approximately the whole foot from ankle to toe, or can have only a few narrow straps. They usually include a single strap or possibly a sequence of straps throughout the toes and the lower half of the foot to hold the shoe to the foot.
