On my first day of riding clipless, about 9 years ago, I stopped at a dead end street and momentarily forgot that I had clipless pedals on, and panicked & fell over on gravel-encrusted asphalt. That hurt.

That experience stuck in my head, and I got into the habit of twisting my feet before coming to a stop. I was leery about clipless pedals until I realized the benefits they have. Going uphills is made easier by the pulling & pushing action. Yeah, there is no going back.

Just stay away from deep-forest trails until you get used to 'em. More pain to be felt doing that, trust me.
