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

• Isaac, Judas, Lazarus, The Lost, Lilith, Apollyon, and The Forgotten: 1.0
• Magdalene and Keeper: 0.85
• Cain and The Soul: 1.3
• Eve: 1.23
• ???, Samson, and Dark Judas: 1.1
• Azazel and Revived Lazarus: 1.25
