Improvements in protective footwear, including work boots or shoes, are disclosed. The improvements include a new heel filler for the heel portion of the sole, the filler being formed of a light-weight moulded plastic material. The heel filler may be easily located in the heel area prior to the final boot forming step. When a shank or protective mid-sole is to be used the appropriate element is provided with a slot or other locating device which may be secured to a cooperating projection on the heel filler so that the two components may be positively located together prior to the final boot forming step. The boot is strengthened by providing a longitudinally extending rib or ribs in the arch region of the shank or mid-sole. The boot is less expensive to produce because there is less possible wear or damage in the production equipment. In addition there are fewer production rejects and the resulting boot is stronger than prior art boots.
