Actress Sandra Bullock is auctioning off her quirky Minion inspired shoes for charity.

The 50-year-old, who plays villain Scarlett Overkill in the new `Despicable Me` spin-off `Minions`, has revealed the bright-yellow pumps she wore to the Los Angeles premiere on Saturday, will go under the hammer at non-profit Los Angeles-based organisation Art + Practice.

The high heels, costing $800, were designed by Rupert Sanderson in tribute to the cute dungaree-wearing creatures with eye designs on the toes and heels, reports femalefirst.co.uk.

"We're going to give all the proceeds to Art + Practice, which is a non-profit organisation here in LA," Bullock told Entertainment Tonight Canada as she walked the yellow carpet.

The Academy Award winner was accompanied by her five-year-old son Louis at the premiere.
