@@christianjaydumalaoron6447 this one is heavier thicker and firmer,it feel less bounce but gave more cushion and propulsion.It feels comfortable enough for walk,easy run and long slow distance
@@christianjaydumalaoron6447 Hi,this one and 2000km both are for beginners but have different characters. 2000 is lighter softer and gives good stability,you can run on faster speed too 4.0 is heavier firmer from lower midsole,it gave more propulsion and Quicker transition than 2000,better stability and lock down your foot better too
@@adrianalcala6258 Ahhh Both are suits for running,it’s depend on your running style and your likes.If you ran with high cadence and short stride,low foot lifted go for Propulsive like Fierce.If you ran with low cadence and long stride length,jumped for next stride go for Blaze
