Lil, Walking in The Boot ( yes, it deserves a capital B) can cause strain in varying parts of the body because your gait is thrown off balance. The Boot is heavy, clumsy, and adds a few extra inches...I don't think it's meant to be used for a lot of walking. I only used the Boot for protective purposes. Are you using crutches to support your weight? That may help.

On Monday, my guess is that your doctor will tell you to change to walking shoes. How many weeks has it been since the surgery?
