Hi I got a C60 EST binding and I am looking for a pair of boots. I only do carving and going down the hill fast. I never do park or jumps. I plan to get burton T6 with c60 binding but I am not sure about the boots. I am not hardcore carver either so how stiff should my boots be? 1-10? I looked up and found Nike zoom force 1 boot stiffness 5 is it good? or should I find another boot? I am looking for responsive boots but at the same time a comfortable one but responsiveness comes first.
