Stephen Curry is not currently sponsored by Nike; instead, he has been a prominent figure for Under Armour since 2013. His decision to leave Nike for Under Armour was significant, as it marked a bold move away from a well-established brand to support a relatively smaller company at the time. Curry's choice was driven by a desire for a more personalized partnership and the opportunity to help build Under Armour's basketball line from the ground up. This decision not only surprised many in the sneaker industry but also showcased Curry's commitment to innovation and his belief in Under Armour's potential to grow in the competitive athletic market. Since then, Curry has played a crucial role in elevating Under Armour's profile, and his signature shoe line has become increasingly popular among basketball players and fans alike.
