Mach supersonic remains a shoe suitable for fast daily workouts or long slow ones.
The profly + midsole differs from mach 4 as it is more reactive and therefore more performing.
Like mach 4 the shock absorbing system keeps the foot closer to the ground.
Upper: the mach supersonic upper is engineered but unlike the basic model it is thinner and more enveloping.
It has been inserted into the tongue and the edges of the same foam have been rounded to make it more ergonomic.
Sole: There were no variations in the sole.
