Riding down the street when a friend of mine on a skateboard turns from the sidewalk to the street, I brake hard to a stop to say hi but forget to un-clip, so i lean on him. I don't touch the ground, But if he would've been a few feet away I would've ended up on the floor.
***If you tipped over/fell while on clipless, you fell cause of the deng clipless. No excuses. You fell, admit it.
