LeBron James' protective father inspired Nike's LeBron 21 'Aragonite' (HF5467-300). Each shade of the low-top model is inspired by seashells and protective crystals, with LeBron's 21st signature edition associated with the carbonate substance 'aragonite'.

Warm 'Terra Blush' detailing on the outsole, upper tongue, heel tab, and delicate Swoosh trim reflects the burnt orange colour of the crystals. From the toe to the collar, the thick canvas material used to create the top has a blue and white ombre pattern. This gives it a denim-like appearance.

Furthermore, a delicate shade of 'Jade Ice/Emerald Rise' adds a pop of colour to the laces, mesh tongue, inner lining, and veined heel counter. Finally, a hint of 'Platinum Violet' finishes off the Zoom Air-supported midsole.
