I am looking at which pair of clipless shoes to get. I am not sure which pair would be best I am looking at pretty much the same shoes but one pair is MTB and the other is Road. I am not sure if the loss in energy transfer is worth being able to walk in them. I ride mostly for recreation and to get two and from work... but also when I am on a quick run for a small purchase at the store. What are others thoughts on mtb vs road shoes?
