LOL! I have a pair of boots just like that. I can't wear them because the sole is gone but cannot part with them.
I was thinking of building a dummy and put it on the front porch in a chair ,just for fun. i could use the worn out clothes and gloves on the dummy.
My dad has a favorite pair of boots he wears to the barn held together by duct tape. He loves them and they don't make them any more!
Like these? On a more serious note.... It's not a bad idea... How to Make Duct Tape Shoe Lasts for Wet Felted Boots or Slippers
