This LeBron 21 is named after the protein fortifying mollusk shells and gets covered in White, Black, Bicoastal, and Photon Dust as the sneaker boasts a White hue all over the upper which has then been hit with a pearlescent finish. For contrast we see the addition of Black on the tongues, laces, inner liner, heels, and midsoles along with Bicoastal hits on the eyelets, medial Swoosh, and heels.
