Light Speed Shoes

The Light Speed Shoes (ライトシューズ Light Shoes) are an upgrade available to Sonic the Hedgehog in the games Sonic Adventure, Sonic Adventure: Director's Cut, Sonic Adventure 2, Sonic Adventure 2: Battle and Sonic Unleashed. In each of these games, they are a pair of shoes that allow Sonic to perform the Light Speed Dash and travel along trails of rings. They are the equivalent to Shadow's Air Shoes.

In Sonic Unleashed they are known as Light Speed Dash Shoes (ライトスピードシューズ Light Speed Shoes), where they are discribed as being made of the same material as rings.

In Sonic the Hedgehog (2006), the Light Speed Shoes are replaced by the Light Chip.

Sonic Adventure
In Sonic Adventure, the Light Speed Shoes are found in the sewers in the Station Square Adventure Field after defeating the Egg Hornet boss. Head down the manhole at the road in the City Hall area. Once down there, head to the end of the sewer and the Light Speed Shoes will be at the platform to the right.

Sonic Adventure 2
In Sonic Adventure 2, the upgrade is found in the Metal Harbor stage. After the first Star Post, get over to the nex platform. The Light Shoes can be found on the top of the tower on that platform, which can be reached with the pully.

Sonic Unleashed
In Sonic Unleashed, the Light Speed Shoes can be found in Shamar, on a cliff to the left after Sonic enters the Entrance stage and is a requirement to reach the next Day Stage. In order to obtain this upgrade, Sonic must either have obtained the Wall Jump Shoes and/or the Air Boost Shoes.

It is only found in the PS3/360 versions, since Sonic already has all upgrades at the start of the game in the Wii/PS2 versions.
