The Portwest FC48 Composite Leather Foundry Boot is built for welding, metal handling and foundry work, where molten metal splash and hot surfaces are part of the job. It offers high protection against molten iron splash. Its leather protective flap releases quickly, so you can get the boot off in under 5 seconds if hot metal gets inside.
Underfoot, a heat resistant rubber outsole copes with temperatures up to 300ºC and adds slip resistance and a ladder grip. Insulation helps against both heat and cold, and a cushioned footbed with padded collar and tongue keeps you comfortable through long shifts. The construction is entirely metal free.
