Magic Speed 4

$170.00Speed Trainer

The ASICS Magic Speed 4 is a carbon-plated super trainer for tempo runs, speedwork, and marathon training, bridging the gap between daily trainers and race shoes. It features FF Blast+ foam with a forefoot FF Turbo insert and full-length carbon plate, offering a firm but responsive ride. Pros include a good fit, stable feel, and durability for frequent use. Some find it too firm or lacking expected propulsion, particularly at slower paces, and it may not be as bouncy as premium race shoes. Ideal for runners seeking a supportive, versatile option for faster efforts without a premium price tag.

Highlights

  • Responsive and snappy ride optimized for faster paces and tempo workouts
  • Stable platform with a wider forefoot and secure heel and midfoot lockdown
  • Durable outsole and robust construction suited for frequent training use
  • Breathable engineered mesh upper with a true-to-size fit

Considerations

  • Firm and dense ride that can feel clunky or unyielding at slower paces
  • Requires a break-in period to soften the foam and improve responsiveness
  • Narrow heel collar may cause slight instability on turns or require a runner's knot for secure lockdown
  • Upper stiffness around the ankle and a very thin tongue may cause discomfort or lace bite for some
