You know what also hurts, getting a pedal into the shins, which is what I expect will happen if you ride flats for long enough.
Failing to unclip happens to everyone at least once, I set the bar high, and have had it happen atleast 5 times. One was a year ago to the day, I’ll take the failure to unclip slow motion fall, over a pedal to the shins any day. One just hurts the ego, the other actually causes pain.
