Clipless pedals are a double-edged sword. With SPD pedals in particular, if the cleat position is wrong you'll be
forced to have it wrong for every single pedal stroke. On the other hand if you get it right, then it will
always be right. I had to fiddle with my cleat position a bit until I got something that was all-day comfortable. When I first installed the cleats, they were extremely
uncomfortable so don't be afraid to play with positioning! You may also find that clipless pedals exacerbate things like leg length discrepancies or footbed tilt. Now that I have everything setup properly, my knees are
much happier with SPD clipless pedals than anything else I've tried.
