Fugly shoes that are bought by parents who copy their child's friend's parents. There is nothing special about the shoes other than the name. The only reason any parent would buy these shoes is to impress the spoiled children of their friends.
This is the jingle lyrics:
Its leli kelly | the cutest shoes | oh yeah | with lelli kelly we are so cool | ooooh lelli kelly | the cutest shoes | oh come play with us | you'll be cool with us | we got the cool gear yeah | oh yeah
