I'm really frustrated as I got rid of my old SPD pedals and cleats and bought Speedplay Zeros. The pedals and cleats were put on by an installer at my cycle shop. I went to use them for the first time last evening and I managed to get my left shoe and pedal to "clip in" with a great deal of effort. I could not get the right side to work at all -- no matter how much pressure I put on it. I thought these pedals were super easy to get in and out of; my first impression is not so stellar. I am I doing something wrong; do I have a bad cleat; will they loosen up over time (make it easier to get into)?
