Well, I made the switch from SPD to Look pedals. The main reason I did it was because the SPD's where causing some serious foot pain right in the middle of my foot after about 2 hours on the bike. It would get to the point of making my toes numb. The LBS told me it was mostly because I was putting all the pressure on one small area and that a bigger cleat like Look would spread it out over a larger area. Plus, they were easier to clip in and out. Unfortunately, I had to buy new shoes to fit the cleats.
So, I was wondering, any tips or things to know when installing these pedals and cleats? I installed my own SPD pedals and cleats with no problems and I assume it will be a similar install with the Look, but I just wanted to ask in case there is something I need to know.
