I was very afraid of getting them and just made the jump two weeks ago to SPDs. Everything was fine and I was doing a great job of getting in and out of them. Until Saturday. Going up a big hill, I shifted wrong (shifted up instead of down). The bike came to a complete stop, and I went to put my foot down, and it didn't move. I said to my friend, "I'm going to fall," and then I did. It hurt. I got up. I walked up the hill and was on my way. If that is the worst of it, I'll be okay.
