How to make a button that makes your character hover?

Trying to make a script like in this game: https://www.roblox.com/games/2147708657/FAIRY-FOREST-STAR-SORORITY

If you click a button it makes your character hover above ground and welds 3D shoes to your feet to give an illusion of standing on heels. I've tried multiple morphing scripts but it just makes the shoes clip into the ground and act weird (even if CanCollide is on)

I honestly have the welding part all figured out but am still stuck on how to make your character hover when clicking a button.

The button part is simple, however with my limited knowledge of scripting I apologize for not being able to answer the second part.

1: Create a ScreenGui inside StarterGui 2: Create a TextButton inside that ScreenGui 3: Add a LocalScript inside

LocalScript:

-- function

script.Parent.MouseButton1Click:Connect(function()

-- any code below, will be placed in effect once pressed.
-- this is where you would apply your "hover script"

--test
print("Clicked")

end)
