The Under Armour Curry 7 ‘Pi Day’ commemorates March 14, a special date that holds a dual significance as both Steph Curry's birthday and the annual observance of the renowned mathematical constant. Stepping away from the basketball court, this version of the popular athlete's signature shoe features a lace-free slip-on design and a sleek, all-black colorway. Adding to its convenience, the shoe includes pull tabs at the tongue and heel, with the latter showcasing the first 30 digits of pi as an inscription.
