AE Grayson sizing/fit compared to Park Avenues or Strands?

I normally wear a 10D in the AE Park Avenues and Strands. However, while the length is perfect, I need to add tongue pads. Is the vamp on the AE Grayson high enough that they will fit like the other AE shoes I have? Should I size down at a 9.5? For what it's worth, I wear a 10 in a Sebago Penny Loafer and the fit is spot on.

Thanks!
