I have never tried special organ shoes for playing the pedals. I've always just played in my stocking feet. As big as my gunboats are, I would probably hit five or six keys at once if I wear shoes. So I go on and on in my socks.
My "gunboats" are size 13, EEE - just for that reason I cannot play in sock feet at all ... Although I was taught the Gleason method of pedaling, I have crossed over in later years to the Stainer method of pedaling which allows one (amongst other things) to use inner and outer parts of ones foot. When I tried the "sock hop method" I kept stubbing my big toe into the sharps ... for me, playing in shoes is much easier than being sock footed.
I have been using Organmaster Shoes for 48 years ... they are strictly for playing ... standing in them for more than 5 minutes is most definitely painful.
I might just have to get a pair of Hannah Montana Crocks though ... :lol: ...
