An ancient proverb once said, "If she doesn't know who Lisa Frank is, she's too young for you, bro." The psychedelic designs that once lined our extremely '90s trapper keepers, notebooks and pencils can now be worn on your feet. Lisa Frank, purveyor of our elementary school supplies of yore, has teamed up with Reebok to reimagine their Classic Leather silhouette through her Technicolor lens.

But there's a catch — not everyone will be able to cop this rare revamp. A select few can get their hands on this nostalgic release by submitting to a social media contest. To enter, tweet @ReebokClassics and @LisaFrank and answer the question: What’s your favorite trend from your back to school days? With only two pairs in existence, an adult and child size, only the most unique answers will win these colorful kicks.

With its trippy puppy, rainbow, kitty, flower renderings, rainbow ombre laces and personal message from Frank, this is a sneak perfect for fashion's current peak '90s revival moment. Will you be entering to win? We sure will be!
