The ASICS Magic Speed 4 stands out as a high-performance tempo and super‑trainer shoe. With a full-length carbon plate, thick cushioning, and stable platform, it delivers propulsion-packed speed work without compromising on comfort or wear-life. Ideal for runners who want one fast shoe that can work hard across long workouts—without the premium price tag of flagship models.
Fit & Feel
The upper in this model uses a light engineering mesh with thoughtful contouring that supports normal‑width feet. The fit runs true to size and offers excellent midfoot and heel lockdown while providing moderate toe-box width and vertical volume, allowing natural foot movement. Though it's not as snug-fitting as racing‑style uppers, it comfortably accommodates most neutral runners.
Ride & Responsiveness
The midsole combines full-length FlyteFoam Blast Plus with a small Forefoot FlyteFoam Turbo insert, layered over a full-length carbon resin plate. This configuration delivers a smooth, energetic ride that rewards faster running while remaining surprisingly stable for longer tempos and endurance efforts. With 44–42 mm of stack height, the ride feels plush yet purposeful—suitable for racing distances from 5K to marathon.
Transitions are seamless and supported by a moderate rocker and a wide-platform design, offering more stability than you’d typically expect in this category. Heavy-footed runners and neutral strikers alike will find the Magic Speed 4 responsive yet reliable, mile after mile.
Traction & Durability
ASICS equipped the outsole with full-coverage ASICSGRIP™ rubber, delivering outstanding grip on wet and dry pavement. Lab-tested friction scores place it among the market leaders, ensuring confidence in varied conditions.
Despite its super‑shoe credentials, the outsole durability is impressive—with minimal wear after extensive tempo and easy-run mileage. The rubber thickness and shock absorption ratings (144 SA heel) suggest the shoe is built to last well into extended training cycles.
🧭 The Verdict
The ASICS Magic Speed 4 is an excellent match for:
-
Runners seeking a carbon-plated trainer that offers tempo and race-day potential without the ultra-high price.
-
Neutral stride athletes who want stable, cushioned propulsion for speed workouts and longer runs.
-
Those who value durability and consistency in a fast shoe—built to handle repeated high-intensity efforts.
It bridges the gap between pure racing flats and heavier super trainers, offering propulsion‑backed speed with more cushion and comfort than lighter tempo shoes like the Magic Speed 3. A solid choice for runners looking to lean in on speed and maintain foot comfort across runs.
