This article is about the attribute. For the challenge, see SPEED!.

Speed determines how quickly the character moves and is represented by a shoe. Speed has a minimum value of 0.1 and a maximum value of 2.0.

Some items may lower the maximum value, and other items may bring it back up, but it can never exceed 2.0.
