Cam Newton trotted out these LTE Gold CN1 "MVP" cleats for pre-game warmups at the Super Bowl. Under Armour put 50 pairs of the autographed cleats on sale after Newton won the NFL Most Valuable Player award on Saturday night and they sold out in minutes with part of the money going toward the Cam Newton Foundation.

More will be on sale soon, although they will not be autographed.

Players are allowed to wear whatever cleats they want during pre-game warmups up until an established period, at which time they are required to follow the NFL's mandatory uniform rules.

Newton typically wears a flashy pair of cleats. In the NFC championship game, Newton wore cleats with his teammmates' names on them.
