Our Verdict

ASICS MAGIC SPEED 5

adidas Adizero Boston 13

The ASICS MAGIC SPEED 5 and adidas Adizero Boston 13 are both moderately stacked super trainers with similar overall geometry, but their underfoot feel is quite different. The adidas Adizero Boston 13 relies on EnergyRods and a much firmer platform that demands more force to really come alive, so it tends to reward powerful runners who can consistently load the shoe. The ASICS MAGIC SPEED 5 uses a full-length carbon plate in a noticeably lighter and lower-stacked package, which makes it feel more efficient and easier to turn over, especially when fatigue starts to creep in. This also means it will feel more at home for short racing.
