The metal worker's choice. A superb shoe for galvanising and welding metal. A closed front flap protects against stray sparks and hot metal splinters. The Mack-M offers enhanced protection for the metatarsal as well as PU outer toe protection and a 'bomb proof' concealed steel toe cap. Internally, feet are kept dry and fresh thanks to the moisture removing properties of Emma's Hydro-Tec® Sanitized Silver.
