Muah-ha-haaa! So these are men's slippers. They look like shoes unless you study them with a magnifying glass. I decided to make them sole-less. So I cut out their rubber bottoms, but left the sides, punched holes through them and laced them up. And voila, shoes you can wear to work, but you are actually barefoot! Well, I do need to make to minor changes. These are shoelaces, I was going to change to tiny, circular elastic instead. And I need to put an elastic loop around the second toe (coming down from the bottom) -so that they don't flip up.
