Men's Orthotic Slide Sandals – A slider is a kind of footwear different from shoes and much like flip-flops. They’re backless and open-toed, essentially an open-toed mule. Commonly, all slides are sandals. Thongs and flip flops are generally classified independently. Slides can be high-heeled, flat-heeled or somewhere between, and may cover approximately the whole foot from ankle to toe, or might have only a few narrow straps. They sometimes include a single strap or a sequence of straps through the toes and the lower half of the foot to hold the shoe within the foot.
