Our Verdict
ASICS MAGIC SPEED 4
ASICS SONICBLAST
The ASICS MAGIC SPEED 4 and ASICS SONICBLAST are both plated performance trainers, but they suit different runners. The MAGIC SPEED 4 is lighter, lower to the ground, and more aggressive at toe-off, making it the better pick for faster workouts and racing. The SONICBLAST is more cushioned, bouncier, and more forgiving over longer efforts. Get the MAGIC SPEED 4 if speed is the priority; get the SONICBLAST if you want a more protective plated trainer that can handle a wider range of running.
