Worn by legendary B-ball players, this '90s-era design featured a look so unconventional that it was called Crazy. Its descendant, the Crazy BYW, combines retro style with innovative cushioning. This bold Pharrell Williams version has a flexible, adaptive adidas Primeknit upper. Boost midsole pods give a comfortable, responsive feel. Inside is a Pharrell signature sockliner inspired by the ancient art of reflexology.
