The Nike LeBron 21 Conchiolin takes inspiration from the microenvironment that allows pearls to form and grow inside a mollusk's shell. A subtle iridescent finish distinguishes the white leather shell, overlaid atop a black mesh base and accented with perforated detailing for improved breathability. A molded Swoosh outlined in black embroidery adorns the lateral side, while LeBron James' signature graces the tongue. The sneaker rests on a lightweight Cushlon midsole, painted black and fitted with Zoom Air cushioning in the forefoot and heel.
