I've had both and they had a pretty similar fit. Ion is a slightly stiffer flex that would probably be better with your Malolo in pow. I did like the grippier Vibram outsole on the Imperial though. The $100+ price difference between the two would prob play a factor in the decision-making process for most peeps though.
