Nerve Ques?

Hypothetical Question, if someone wanted to hide something in their shoe, roll it up in 1 sock and put it underneath their feet in the shoe, but it would have to be there for 2wks to a month and u have to walk with it for about 6 hours a day each shoe, would this cause any damage to the nerves in the foot or the spine or anything like that because you are standing on a raised surface (rolled up sock)?
