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.
