How to Make "slide Shoes"(my Way)

Hey guys,today I saw a "soap shoes" 'ible and decided to make my own version since I don't have plastic "boards" .Materials:
A couple of eyes
A functioning brain
Lots of thumb tacks
Shoes that you don't mind ruining

I decided to use the sides of the holes as marks to put the thumb tacks. You can do one then push with the other like on a skateboard.
P.S:I am not responsible for any injury caused since you decided to make it and use it but if you used it and werent injured,feel free to comment on this 'ible.
