The Hurricane is a good choice for long runs and also for occasional runners. Unlike the lightest racing and training shoes, the sole has plenty of rubber to extend the shoe's lifespan. The midsole uses two different types of cushioning foam: PWRRUN PB foam is in the upper part of the structure and PWRRUN EVA foam is in the lower part. This combination provides good shock absorption but also some responsiveness. - Regular fit - Formfit upper conforms to the shape of your foot - "Center path" design: the sole is fairly wide, and its edges rise to the sides of your feet - "Rocker" design speeds up the transition from landing to takeoff - Sole thickness is 38 mm at the heel, 32 mm at the forefoot, drop 6 mm
