Sforno on Genesis 29:1/ספורנו על בראשית כ״ט:א׳

1וישא יעקב רגליו, when a person proceeds on a journey voluntarily, at his own initiative, this is described in terms of his personality carrying, lifting his feet. When the initiative is not his, even when he does not march involuntarily, under orders against his will, his feet are described as carrying him, i.e. his personality, the rest of his body.
