Honestly, i popped my shoe out with no issue. Slowly and evenly pry between the donor hull until you only have the shoe arch to separate and the pry left, right and so on till it pops. Razors, flat head drivers and plastic shims worked well for me. 2 hours time, but look at it like you’re paying yourself by getting it done.
OR
USE THE DONOR PLATFORM! (I didnt have one to swap into)
