Hinged shoe sole assembly for working boots |
摘要 |
A working boot designed such that the bottom of the foot of a wearer will be completely shielded by a metal sole yet still be capable of full, free movement. The shoe sole structure hinges a forward sole section to a rear sole section such that the straight hinge line passes below the lowest points of the first and fifth metatarsal heads of the foot of a wearer. It was found that, in order for a completely flat sole to work, the horizontal length of the hinge must be equal to the vertical thickness of the sole sections.
