how do you compare a casual shoe to that of a performance shoe? i assume which ever you get is casual but i find it difficult to choose since i would rationally think that if you get the 2k4, for casual, it would also be used later down the line when you decide you are done sporting them around casually for basketball, so the obvious choice in my mind would be the 2k4.
