Speed feels natural in the ASICS Sonicblast. Ready to graduate from everyday training shoes to something snappier? The Sonicblast combines the familiar comfort of FF BLAST MAX cushioning with ultra-bouncy FF Turbo² foam and a flexible Pebax Astroplate to create a springy ride that thrives at faster paces. In our ASICS Sonicblast review, wear-tester Heather said "The FF Turbo² foam felt light and responsive, and it's just an exciting shoe to run in." Details: Upper: The jacquard woven construction delivers that "just right" Goldilocks fit—not too loose, not too tight, but perfectly dialed in. The traditional feel includes a thin, stretchy tongue and slightly padded heel collar that disappears on your foot once you start moving, letting you focus entirely on your run. Midsole: The innovative dual-layer design places FF BLAST MAX on the bottom for stability and familiar comfort, topped with FF Turbo² foam for that wild energy return. The teardrop-shaped Pebax Astroplate flexes naturally between the layers, creating an experience that's firm and engaging without feeling harsh or unforgiving.Outsole: ASICSGRIP technology gives you the confidence to tackle any surface, so you can focus on enjoying your run instead of worrying about your footing.
