I'm not really sure what the intent of those pedals is. I mountain bike offroad with clipless pedals, shimano m520s The only time I unclip is when I need to throw a foot down to stop myself from falling. This usually happens when I can't quite get over something steep, and I've stopped moving forward. If I'm riding something fast and or technical I'm definitely clipped in. At least with my shimano pedals I can clip out really fast when I need to.
