march out of one’s feet
v. phr.— «We received a cell phone photo message from Duncan. It was a picture of his feet. Silver dollar sized blisters had formed and torn away all over both feet. Blood had soaked his socks and boots. He had, in military parlance, “marched out of his feet.”» —“The Brave and the Not-so-Much” by Patrick Mead Patrickmead.net Feb. 11, 2008.
