I will 'third' the comments about lube. I know it's time to reapply when I notice it's becoming slightly difficult. When properly lubed, they snap right in. They do take a week or two to break in too. I had the same problem when I first got them. Two trips to the LBS and numerous phone calls to Speedplay. I just wasn't hitting them right, but once your muscle memory kicks in, it's mindless.
