Sam Edelman Henna Slide Sandal – A slider is actually a type of footwear distinct from shoes and comparable to flip-flops. They’re backless and open-toed, basically an open-toed mule. Normally, all slides are sandals. Thongs and flip flops are commonly categorized independently. Slides can be high-heeled, flat-heeled or somewhere between, and could cover around the entire foot from ankle to toe, or could have only a couple of narrow straps. They sometimes include a single strap or a sequence of straps across the toes and the lower half of the foot to carry the shoe to the foot.
