Okay, I made him stop when he goes fast enough, and when you go to a boss stage, the spring shoes stop, and when you go to the stage after that, they start again. To do this though, they had to be turned into wad files, but the original soc files are still in there, so I'm not sure if they go here anymore. The link in the third post has been updated. The soc called normal can be used to fix effects on running frames, and was used in the wads.
Also, the description is that Sonic now has the same spring shoes he had in... I can't remember the name of the game, but I unlocked it in SADX, but this time, they deactivate when his speed accelerates past their abilities. (Did I spell that right?)
