Muktza is not a problem even according to the Chazon Ish, who prohibits moving muktzah with any part of one’s body (except in a case where he sits on a bed where there is straw, and the straw happens to move a little, or a similar case) since here he has no intent at all to move muktzah and he is moving it indirectly and incidentally (in the course of walking).
