Air Boost Shoes

The Air Boost Shoes are an upgrade for Sonic the Hedgehog (character) in Sonic Unleashed. This upgrade needs to be found in the 360/PS3 versions of the game, but in the Wii/PS2 Sonic already has the upgrade. This item can be found in the Chun-Nan Adventure Field and can only be reached after getting the Wall Jump Shoes. This item allows Sonic to use his Boost ability while in the air, which can be very useful such as by getting to the next day stage in the same area.
