Stamos' left shoe is a shiny leather lace-up style with a pointy toe front, whereas his right foot has a wedge rear heel, round-shaped toe and a dull surface (looks like he's wearing a black sock under the straps of a black ankle brace style boot with an open top/front on his right foot).
You can't see his other shoe, how do you know it's not the same as the so called "boot"?
