Made for kids, the adidas RapidaLux S and L EL K 'Core Black' features a full-length Boost midsole that delivers energy return and a cushioned ride. Up top, the sturdy build combines breathable black mesh with matching black suede overlays at the toe and heel for added durability. A heel loop is good for easy on and off, while elastic laces and an adjustable strap that wraps over the tongue provide a snug, comfortable fit.
