Safety footwear having metatarsal guard, and methods |
摘要 |
A metatarsal guard inserted in the upper of a safety shoe is made of plastic and defines an arch extending from the sole of the shoe on one side of the wearer's instep to the sole on the other side of the wearer's instep. A rear portion of the metatarsal guard includes at least one longitudinal tongue extending away from the toe portion of the guard, preferably three tongues. An appropriately sized metatarsal guard is used for each size of footwear. The guard is shaped and size by the last used to make the footwear.
