The NATIONAL SAFETY APPAREL L68FA01MD is an aluminized overshoe designed to protect footwear and feet from radiant heat, molten metal splash, and high-temperature environments. Constructed with an aluminized fiberglass upper, it reflects intense heat while maintaining flexibility during wear. Standing 11 inches tall, the overshoe slips over existing work boots without requiring specialized footwear, making it a practical solution for foundry workers, welders, and industrial technicians who need quick-on protective coverage. The non-slip sole adds stability on surfaces common to hot work environments.
This overshoe is sized for medium in both mens and womens shoe sizing, making it a versatile fit across a broad range of workers. It is suited for use in foundries, steel mills, smelting operations, glass manufacturing, and other industrial settings where workers face exposure to sparks, slag, or radiant heat at floor level. The plain toe construction keeps the profile low-bulk for ease of movement. Weighing approximately 2 pounds per pair, the unit stays manageable during extended wear.
Designed as an overshoe-style protective cover intended to fit over standard work boots sized medium for both men and women. No specific footwear model compatibility was provided by the manufacturer for this SKU.
Overshoes should be donned before entering high-heat or molten-splash work zones and inspected for tears or delamination of the aluminized layer before each use. Damaged overshoes should be removed from service immediately. No tools are required for fitting, but ensure the overshoe sits securely over the boot with the non-slip sole making full contact with the walking surface. Follow your facility safety plan and applicable OSHA PPE standards when selecting and using aluminized protective footwear.
