I have ecco soft 7. Compared to soft 7, this Colin 2.0 is much lighter and has thinner leather so I can wear it in summer. In my opinion, Colin 2.0 is not as complex as soft7. I would not do exercises that require right and left weight shifting, such as e.g. football. I have a wide foot, width 11cm x length 255cm, size 7-7.5 fits my foot perfectly.
