There’s a new Nickelodeon x Super Heroic collaboration, and it’s inspired by slime.

The new colorways of the Super Heroic TMBLR V 2.0 shoe will debut at Nickelodeon SlimeFest in Chicago and are inspired by the ever-popular signature pink and green slimes. “Nickelodeon Glitch” (green) and “Nickelodeon Light Speed” (pink) will be released on June 8 and will be available exclusively in-store at Kids Foot Locker, as well as online at the Kids Foot Locker and Super Heroic websites.

Families in attendance at SlimeFest can enjoy a Slime Maze, presented by Super Heroic. Jason Mayden, co-founder of Super Heroic will be in attendance at the event.

The shoes will retail for $69 and will be available in sizes ranging from 12C to 7Y.

Nickelodeon SlimeFest is a two-day, family-friendly music festival, on Saturday, June 8, and Sunday, June 9, at the Huntington Bank Pavilion at Northerly Island in Chicago. For its second round in the U.S. (it’s a long-running affair internationally), Grammy Award-winning artist Pitbull, singer/songwriter Bebe Rexha, Nickelodeon star and YouTuber JoJo Siwa, and Grammy Award-winner T-Pain will perform.
