Same thing happening with my '01 cool grays but to separate sole place over a pot of boiling over so the sole can come off then apply salon care 40 to unyellow the soles. To reattach use cement glue, I use barges (you can buy at home depot) make sure the shoe is aligned perfectly with the sole...
For the air bubble id use a hair blow dryer and blow the bubbles till they clear up. itll take 2 mins or so. For the mesh and leather cleaning id use reshoevn8er or air legends. Also their sea glow but considering the price just stick to salon care 40
