The ASICS Sonicblast 2 is a high-stack, plated running shoe with a clear focus on speed, but it manages to offer more versatility than you might initially expect. The easiest comparison is almost a plated Novablast, although there are enough differences to give the Sonicblast 2 its own distinct character.
The Ride: Springy and Propulsive
When standing or walking around in the Sonicblast 2, the rocker does not feel particularly aggressive. Once you start running, however, it becomes much more noticeable and begins to push you naturally through your stride.
The trampoline-like pod in the forefoot is a particularly noticeable part of the ride. When you land and transition onto it, there is a springy sensation beneath the foot that provides plenty of bounce and helps propel you forwards.
Performance: Built for Speed, but Surprisingly Versatile
The plated construction and responsive forefoot make the Sonicblast 2 feel naturally suited to tempo sessions and interval runs. There is enough propulsion to make faster efforts feel enjoyable, and it could comfortably be used as a race-day option as well.
What surprised me is how comfortable it remains when you are not pushing the pace. Despite being a more speed-focused shoe, it still feels good during slower running, giving it considerably more versatility than a dedicated racing shoe.
Stability: Reassuring for a High-Stack Speed Shoe
With its substantial stack height and faster-running focus, you might expect the Sonicblast 2 to sacrifice some stability. In reality, it feels surprisingly stable for this type of shoe, providing a reassuring platform without taking away from its lively character.
That balance makes it easier to use across a wider variety of sessions, rather than feeling like a shoe that needs to be saved exclusively for your fastest days.
Upper and Comfort
The upper has also improved from the first version, with better breathability helping keep the shoe more comfortable as the intensity and distance increase.
Combined with the stable platform and responsive cushioning, it helps make the Sonicblast 2 a performance-focused shoe that remains comfortable enough for more regular use.
The Verdict
The ASICS Sonicblast 2 offers a very appealing combination of high-stack cushioning, a plated and responsive ride, and enough stability to make it feel controlled when the pace increases.
It is at its best when used for tempo runs, intervals and faster sessions, but its ability to remain comfortable at slower paces makes it a genuinely versatile option. If you like the lively character of something such as the Novablast but want a more propulsive, speed-focused experience, the Sonicblast 2 is well worth considering.
