The toe portion of shoes used industrial applications or used in mines shall be sufficiently rigid so as not to get pressed down beyond a specified limit when a heavy block falls down on it, thus preventing crushing of or injury to the toe of the user. The toes of miner's safety boots or industrial shoes are generally reinforced with steel toe cap to provide rigidity to them. Whether these toe-caps are sufficient robust so as to fulfill their desired function is ascertained by subjecting the toe-cap assembled in a cut-out shoe to an impact by a falling weight in suitable equipment. The toe-cap shall not press down beyond a specified limit during the impact.
