They look nearly identical to Power Sneakers, except they use the power of the Gems along with the Light Chip and Antigravity upgrades to give the wearer different abilities. Sonic obtains these shoes from Alberto Robert in Castle Town, Soleanna, as a reward for testing them out in his first Town Mission, "The winder of a Shoemaker". They are needed to obtain the Light Chip and enter Wave Ocean.
After the events of the game, it is unknown whether Sonic keeps the Custom Shoes or continues to wear his regular Power Sneakers due to their very similar appearances.
- Sonic uses the Custom Shoes for all but one upgrade in the game.
