2-Shoe Rotation Strategy
Both models occupy the exact same max cushion slot on your shoe rack. Rather than buying both, runner consensus suggests picking the lighter Superblast 2 (249g) for quicker cadence, or the GEL-KAYANO 31 for its FF BLAST PLUS ECO foam with PureGEL rearfoot insert and 4D Guidance System ride feel and structure.
