Superblast 2
The Superblast 2 utilizes FF TURBO+, the same high-performance PEBA foam found in elite marathon racers, but without a restrictive carbon plate. This creates a high-longevity trainer that maintains its energy return significantly longer than standard EVA-based shoes.
Quality & Materials
Features FF TURBO+ foam (PEBA), which is lighter and more resilient than the FF BLAST+ found in cheaper models. The AHAR+ outsole rubber is specifically engineered for high-abrasion resistance.
Evidence & Testing
Tested extensively at the ASICS Institute of Sport Science (ISS) in Kobe, Japan. Independent lab testing by RunRepeat confirms a 28% increase in energy return over traditional foams.
Brand Transparency
ASICS provides detailed breakdowns of their foam chemistry and sustainability reports. The shoe is marketed with specific stack height (45mm/37mm) and drop (8mm) data.
Value Assessment
At $200, it is expensive, but the PEBA foam's resistance to 'packing out' means the shoe often lasts 400-500 miles compared to the 300-mile industry average.
Why Not Alternatives?
Most 'super trainers' use lower-grade EVA blends or include harsh carbon plates that can lead to foot fatigue; the Superblast 2 offers the highest energy return foam available in a stable, daily-use geometry.
