I use the look Keo's on my bicycle. I was very hesitant to go to the clipless pedals believe me! But now that I know what I am doing, I am glad I did.
I was so terrified, that I made sure my husband held the bike while I practiced getting in and out before I even attempted pavement. Then I went to the local parking lot and did enough turns around it to feel comfortable. Then, I practiced starting and stopping as if I was at a stop light. When I was ok with that, then I finally went for a spin in the neighborhood. From there my rides became longer.
Beware, you will probably fall down at some point, I did. I was told I would eventually. We all have at some point. Just be sure to take one foot out before coming to a stop light or sign. This way you have control of you and the bike before stopping.
I hope this helps.
