Sole Power is episode 19 of Season 1 of Sonic Boom, the CGI comedy series made by OuiDo! Productions with Sega of America. It premiered in the United States on 28 March 2015 on Cartoon Network.
Synopsis

Imagine being the fastest thing alive and suddenly unable to run. Every time Sonic hits top speed an ear-splitting whine goes off, bad enough to send the voice-controlled Tailsmobile careering towards a volcano. A battery of tests in the workshop explains nothing, and Sonic is banned from running.
Walking is torture, and sitting out a Crab Bot attack is worse, especially once Sticks ties him to a tree for back-seat driving. So when Eggman, lounging on a beach chair and feeling unneeded himself, offers a sympathetic ear, Sonic takes it. The doctor diagnoses an age-related condition with a very long name and prescribes a cure in the form of new footwear. The noise stops.
Of course they are a trap. The shoes can’t be taken off, and every step Sonic takes charges up Eggman’s Giant Robot, which keeps going on stored power even when he stands still. The doctor, it turns out, was playing the noise himself, though Amy smashes his hologram before he can finish explaining. Sonic’s counter-plan is simple: feed it more power than it can take, running faster and faster until the thing blows up.
