asics NOVABLAST 5 27cm Only used for a 5km test run, but selling because the size didn't fit. Thank you. The NOVABLAST 5's midsole and outsole features and structure pursue a bouncy run, injecting vitality. The FF BLAST MAX in the midsole provides a soft landing and responsiveness, supporting a comfortable run. The upper uses engineered mesh, improving stretch and breathability. The tongue wing construction is adopted to suppress the movement of the tongue and improve the fit.
