Inspired by the laid back vibe of Los Angeles, it's a perfect fit every time with the El A Slide, as its upper is made out of a water resistant, engineered molded foam and textile material, butter soft micro-suede lining and an adjustable velcro strap for all day comfort and fit. It also uses Rekofoam™ which provides 24 hour cushioning, support, durability and recovery within the midsole and outsole.
