I found some images online of shoes (slippers) made from jeans, but I couldn't find any tutorials!
so I played around, and made these out of some old acid washed jeans. They have two layers of white sticky-white crafts foam as a soul, and added black craft foam pads to the heel and ball of foot. I just sewed the craft foam right to the edge of the shoe. I use the belt looped waist as the edging, and the back of each shoe has a belt loop. toes of shoes where made from back pockets.
