The Nike LeBron 21 GS 'Purple Rain' is a tribute to the legendary Prince, an American pop artist whom LeBron loves. The shoe is made of a matte leather construction in the colour 'Violet Dust', this flows into the colour 'Purple Cosmos' for both the heel and sole. Details come in the colour 'Melon Tint', such as the embroidered Swoosh and the lines on the heel. The patch on the insole is another reference to the aforementioned artist, complete with his signature rings.
