Right now I am riding with running shoes but I am going to upgrade to the shoes that clip in. I don't know what they are called but I notice that there are a variety of styles. Look? Spd? Speedplay? and more. What is the best peddle and what do the different styles do? I don't care so much about cost but I want something that makes sense. I am also going to talk to the "guys" at the bike shop but sometimes they look at me a bit strange. Maybe they aren't used to women being seriously interested in gear.
