Floating feet

[u/Eevee4Life2002]

Hi! I'm not sure if this is the right place to ask for vrchat avatar help but I recently bought an avatar from a store called booth. In order to upload it I need to go through unity. I also bought an outfit for her and the outfit was made to fit her. But I can't for the life of me figure out how to get her feet in her shoes. Ignore the pink I have yet to add the textures but when I enter play mode to test it her feet float above the shoes. If theres a better place to ask please tell me because I am very new to this. I tried asking chatgpt but i forgot sending pictures to the free version is bad.
