Sonicblast

$180.00Speed Trainer

The ASICS Sonicblast is a high-stack (46mm heel, 8mm drop) speed trainer featuring a dual-density midsole of FF Turbo² foam over FF Blast Max, a 3/4 length Pebax "Astro Plate," and a breathable jacquard mesh upper. Aimed at runners seeking a stable yet cushioned experience for daily mileage and longer, steady runs, it particularly appeals to heel-to-midfoot strikers or those desiring more structure than the Novablast. While some praise its comfortable, bouncy, and versatile ride for various paces, many reviewers describe it as firm, sluggish, or "blocky" at faster efforts or very slow jogs, with its plate often prioritizing stability over propulsion and a higher price point noted.

Highlights

Stable and secure ride, particularly beneficial for heel strikers and heavier runners
Versatile across a wide range of paces, from easy daily miles to tempo efforts and long runs
Breathable jacquard mesh upper with true-to-size fit and secure lockdown
Excellent traction from the ASICSGRIP outsole, performing well in varied conditions
Plush yet responsive cushioning from the dual-foam midsole, especially noticeable at moderate paces

Considerations

Firm and rigid ride that may feel blocky or lack fluidity, particularly at slower paces
Heavier feel and sluggish response at faster speeds, making it less ideal for racing or quick workouts
Flexible Pebax plate prioritizes stability over snappy propulsion, which may disappoint runners seeking a highly responsive plated trainer
Forefoot area may feel narrow or lack sufficient room for some foot shapes
Initial firmness may require a break-in period to soften and adapt to the runner's stride
