I bought these from Champ Sports when they first came out. I wore them a handful of times but are in good shape. The Nike LeBron 12 “23 Chromosomes” in Black/Pink/Blue is a high-top sneaker with a multicolor pattern, featuring a stylish lace-up closure for a secure fit. With a UK shoe size of 10 and US shoe size of 11, this athletic shoe is perfect for basketball and other activewear occasions. Released in 2015, this model from Nike’s LeBron product line boasts a rubber outsole for durability and performance on the court. The unique design concept of 23 chromosomes adds a sporty and dynamic touch to this popular shoe silhouette.
