To make a long story short the shoes I decided I liked the best would not work with MTB pedals so I got these Shimano R540 Spd SL Road Pedals Black. The shop guy made sure they were on their loosest setting, but I still seem to be having a heck of a time getting my left foot out and it seems to me that I have to give both sides a good hard yank to get out, but it doesn't always work with the left foot. In fact, a lot of the time it doesn't. Suggestions?
