Catrin and PLL....One of factors I'm wondering about is whether the cleat could be at least part of the problem.

My right leg is my dominant leg, and the one that I unclip first/most. In simply looking at the two cleats I can't see any difference in terms of wear, but maybe it wouldn't be particularly noticeable to a novice. I read a bit about SPD cleat wear last night and one of the main symptoms of wear is having a harder than usual time clipping in or out---that hasn't been a problem so I'm not sure whether the cleat itself is an issue. I'm pretty new to cleats so don't have much experience to help me judge. Swapping out old cleats for new is relatively easy, of course, so that's on my list of possible remedies.

On yesterday's ride I intentionally snugged up the front strap of my right shoe, over the toes, just to see if that would make a difference. In doing so, I *thought* I noticed a bit of looseness between the shoe and the pedal. (Versus the foot lifting slightly in the shoe.) I'll ride again this week when it cools down a bit and see if I can detect exactly where the slight looseness is located: foot in shoe, or between shoe and pedal...or possibly both.

My shoes (Rampas, I think) don't have a heel strap so I'd probably have to do something about the insole to give me a snugger fit at the back if I'm either sliding forward or lifting my heel up. I searched here on TE and saw a number of posts about Specialized's various insoles, as well as the Louis Garneau "customizable" insoles that can be heated up, then cooled while wearing, to get a good fit.

Thanks!
