I am pretty sure my saddle had slid down some because it is a mountain bike and I have had some wrecks that made the saddle go sideways plus you're hitting bumps. She is a coach/personal trainer but I know better than to let someone eyeball your fit and move stuff! And I can't really tell on power one way or another but I know the foot pain is new. I have a great relationship with my LBS so maybe they won't charge me the $40 re-fit fee. They don't write down measurements but I will. It is so frustrating because I think it was too low but now it has to be the foot pain trigger. I honestly didn't think mountain bikes needed the dialed in fit quite as specifically as road bikes. On my road bike 1/4" stopped knee and foot pain.
