Old Norse skor, Danish and Swedish sko, Old Frisian skoch, Old Saxon skoh, Middle Dutch scoe, Dutch schoen, Old High German scuoh, German Schuh, Gothic skoh). No known cognates outside Germanic, unless it somehow is connected with PIE root *skeu- "cover" (cf. second element in Latin ob-scurus).

To stand in someone's shoes "see things from his or her point of view" is attested from 1767. Old shoe as a type of something worthless is attested from late 14c.

The verse has accordingly been rendered "iron and brass shall be thy fortress," or, as in the Revised Version, "thy bars [marg., "shoes"] shall be iron and brass."
