I had this problem.
We don't wear shoes in the house in Hawaii. We didn't in Illinois either but anyway, it's something we grew up with.
It was getting to be such a chore to clean the bottoms of my boot cast every time I went out of the house. Since I sleep with it on, we didn't want to bring outside dirt into our bed either. A little bit of thinking and I had the idea to make this denim covering for my boot cast. I put an extra tough material on the bottom to keep it from tearing and it's worked great.

Depending on how many other people break their foot or leg, I could go into business. LOL!
