Is it permissible for a worshiper to place his shoe in front of him as a sutra?

The sutrah for the worshiper is permissible with anything, even with an arrow, a thread, the edge of a prayer rug, or even a drawn line. All of this indicates that a large sutrah is not a condition; rather, anything that signifies covering is sufficient. As for sandals, they should not be used as a sutrah, because they are commonly considered dirty, and they should not be placed in front of the worshiper while he stands before God.
