Okay, that tells me the components of your PB will in fact engage the front shoe.

I don't have a 'new' shoe to measure; however, I took some pics with measurements for the sake of comparison. The thickness of the pad material is about 3/16" on the used shoes in the pictures.

See my next post for additional photos, thanks,
