The Jet Anklet is an upgrade available to Tails in Sonic Adventure. It enables the fox fly further by boosting his speed while in the air. The upgrade attaches a pair of metallic boosters to the back of Tails' sneakers.
- Function: Increases Tails' speed while flying.
- Location: Station Square Adventure Field. Near Twinkle Park, there is an area that leads to the sewer underneath. Inside, there will be a small opening in the ceiling. Fly up in there and the Jet Anklet is right inside.
- Requirements: None.
- Required For: Nothing--it's purely a novelty item to make Tails' life easier when flying, although it is very useful for the long jumps between buildings in Speed Highway.
