I am looking to make the change over as well. I bought my first road bike a couple of months ago and I really need to get rid of these toe clips. I went by my LBS today and I'm stuck on which route I should go: SPD/MTB shoes or SPD-SL/Road shoes. I've heard the advantages and disadvantages of both systems for road bikes but I'm still just not sure on which system I should get. I really don't see myself walking too much on the shoes, but at the same time, I'd like to know I can walk some distance in case of an emergency.
As a beginner rider, would it even really matter? I don't plan on competing any time soon. Which pushes me towards the MTB shoes. But will I be sacrificing comfort? UGH!
