ASICS Sonicblast 2

Description

The ASICS Sonicblast 2 is a high-performance “super trainer” designed primarily for neutral runners looking to tackle faster sessions, tempo runs, interval workouts, and long-distance training.

Key Features

• Dual-Layered Midsole Construction:
  • Top Layer: Features ASICS’ energetic FF Turbo Squared (FF Turbo²) foam right underfoot, delivering high energy return and a bouncy feel.
  • Bottom Layer: Utilizes FF Blast Max foam closer to the ground to provide a reliable, structured landing platform and structural stability.
• Forked ASTROPLATE Technology: Embedded in the midsole is a flexible, lightweight Pebax ASTROPLATE. Its redesigned forked shape allows more of the bouncy FF Turbo² foam to extend through the shoe, creating a pronounced forefoot trampoline effect.
• Forefoot Trampoline Pod: The specialized front pod design leverages the top foam layer to capture and return energy aggressively at toe-off.
• Lightweight Engineered Mesh Upper: Built with a thin, highly breathable mesh that wraps securely around the foot while dropping excess weight. It features a softer, more flexible hand-feel compared to the stiffer upper of the first generation.
• Technical Specifications:
  • Stack Height: Max-stack build (approx. 46mm in the heel / 38mm in the forefoot for men).
  • Drop: 8 mm.
  • Weight: Approximately 242 grams (8.5 oz) for a standard Men’s US size 9, making it lighter than its predecessor.

Key Benefits

• Propulsive, Speed-Focused Ride: The combination of the forked Pebax plate and high-bounce foam naturally encourages you to pick up the pace, making it effortless to transition into faster tempos and race-pace efforts.
• Reduced Leg Fatigue on Long Runs: Thanks to the massive max-stack height and premium cushioning foams, it provides ample impact absorption, keeping your legs feeling fresher over high-mileage runs.
• More Forgiving than Carbon Racers: Unlike stiff carbon-plated marathon shoes that can feel aggressive or unstable on daily paths, the flexible Pebax ASTROPLATE gives the Sonicblast 2 a snappier yet more natural, forgiving feel.
• Weight Savings: Shedding grams from the original version results in a nimble, airy feel on-foot that won’t weigh you down during intense intervals or track sessions.
• Secure Lockdown: Improved engineered mesh and secure textured laces eliminate foot slippage and minimize hot spots during high-speed efforts.
