The Nike LeBron 21 ‘Abalone’ continues the oyster shell theme that serves as the design inspiration for the low-profile silhouette. A swirling blend of blue and aquamarine hues permeates the upper, featuring a leather exterior wrapped around a lightweight mono-mesh build. Perforations on the medial Swoosh offer enhanced breathability, while a 360-degree zonal cabling system provides midfoot containment. The sneaker rests on a Cushlon midsole, which houses a Zoom Turbo unit in the forefoot and a bottom-loaded Zoom Air unit in the heel.
