The ASICS MAGIC SPEED 4 shoe is designed to support your racing goals. In addition to the softer cushioning experience, this shoe helps create better stability throughout your stride. A sculpted carbon plate is designed to help improve stability and propel your foot forward. This helps create a smoother and more propulsive experience during the toe-off phase of your stride. Additionally, this shoe is updated with FF TURBO cushioning, which helps you experience a more energetic toe-off during tempo runs and races.
