The Mystery of the Missing Hi-tops Adventures of Sonic the Hedgehog : Season 1 Episode 44

There's going to be some sort of fair in Sonic's honor today on Planet Mobius, but Sonic wakes up and finds his shoes gone! He suspects Robotnik, but he can't run without the shoes due to the fact that the friction would tear his feet up, so he has to use detective work. He realizes it was a pushy carnival salesman. He admits to having stolen them as he was going to cut them up and sell them as souvenirs.
