It depends on the colour. It's almost like an optical illusion. When I first saw the Orange Challengers, they definitely looked "fat and flat" and I did say, "ugh" more than a few times. The Black or Red Challengers don't look "fat and flat". They look much more proportioned to me. I haven't seen the Plum or Pink Challengers in "the flesh" so I am reserving my judgement until then. But I still want one!!!
