Power-absorbant Insoles

Power-absorbant insoles were used for a pair of shoes that Dr. Eggman created in the Sonic Boom television series. They were given to Sonic the Hedgehog in order to stop a loud noise that happens when he runs fast.

Description
The shoes appear orange with turquise pattern. They are fitted with red lights and made with the power-absorbant insoles which is grey in colour. When worn they prevent the loud noise heard known as the velocity-to-energy ratio incompatibility, a phenomenon that Dr. Eggman said to happen to Sonic due to age.

The shoes also serve as a conduit for energy to the Giant Robot that Dr. Eggman built. The faster Sonic goes, the more power he will generate for the robot.

History
Dr. Eggmans latest trap to stop Sonic involves tricking Sonic into exclusion from his friends due to causing a loud noise to happen whenever he run and pass it off as "velocity-to-energy ratio incompatibility", supposedly what happens to those with super-speed when ageing. Dr. Eggman gained Sonic's trust and gave him a pair of specially made shoes with the power-absorbant insoles which allows Sonic to retain his speed but without out noise to happen.

While the shoes did grant Sonic his speed without the noise, the shoes were also the scheme for Dr. Eggman to draw power directly from Sonic's speed to the giant robot he made. The machine grew stronger the faster Sonic moved and was able to store power for when Sonic was still. Sonic attempted to remove the shoes only to find he could not remove them from his feet. Failing to remove the shoes and his speed only makes the robot more powerful, Sonic used the shoes energy to his advantage and gave the giant robot so much power that it overloaded. After destroying the robot, Sonic went off for a run with the shoes.

Trivia

 * The shoes turning Sonic's strength into his weakness as well as being locked onto his feet are similar functions to the Slow-Down Boots in Sonic Labyrinth. While the shoes do not slow Sonic down, they are stuck to his feet and serve a purpose in favour for Dr. Eggman.
 * Dr. Eggman would of explained how he caused the "velocity-to-energy ratio incompatibility" but Amy destroyed his presentation before he had time to explain.
