Under Armour helped Stephen Curry celebrate his 30th birthday this week, with the unveiling of his latest signature shoe, the Curry 5.

Dubbed the Curry 5 “Pi Day”, the brand delivered 314 pairs of the shoe, which was inspired by the ancient Pi equation of “squaring the circle” and the desire to give Curry the support necessary to “achieve the impossible” on the basketball court.
The sneaker sports a “Black/Metallic Iron” colorway features the symbol, numbers of Pi “3.14.18”, and the Pi number sequence at different points on the shoe.
