Interchangeable Sweater Boots

I love sweater boots, but I wasn't about to buy more shoes so I can make more to go with my wardrobe. I only have one sleeve done, haven't gotten around to making any more. I made the boots using Naimh O.'s project. Instead of gluing the sweater to the shoe, I used Velcro. The velcor had a very stick back but I used a fix all adhesive. Same as super glue but is thicker and doesn't dry as fast.
