Going barefoot, especially as a religious practice of poverty and humility.
From Late Latin 'discalceatus' (without shoes), used especially for reformed Carmelite and Franciscan orders. The term became fixed in English through religious texts.
The 'Discalced Carmelites' are a real order founded in the 1500s, and their very name means 'barefoot'—so this obscure word actually names millions of people and institutions that exist right now.
