Whatever floats your boat, but I disagree. As someone above said, one foot is clipped in the entire ride. The other foot clips in and out as necessary and is so routine I don't even have to think about it. It is as integrated into my ride as shifting and braking.
exactly, it is all how it feels, for some reason I am just more relaxed without clipless. When I put them on, I feel all cranked up and to quote Ricky Bobby, " I wanna go fast!". And that is not my attitude toward my commute. I like to average around 14-15mph, not fly to work.
