Problems solved by technology

When wearing conventional safety footwear that include puncture protective soles, workers often experience discomfort since the protective sole prevents the escape of heat and moisture generated by the wearer's foot and motion.
Metal plates in particular create discomfort since the metal readily conducts cold and heat and therefore modern safety footwear generally uses multiple puncture resistant woven fabric layers that reduce thermal conduction as well a

Embodiment Construction

[0024]FIG. 1 shows an air exhaust outsole made of three layered components, namely, the air ventilating midsole 1, the puncture resistant layer 2 and the tread layer 3. The puncture resistant layer 2 is located away from the wearer's foot to enhance comfort since the midsole 1 can provide air ventilation and cushioning between the foot and puncture resistant layer 2 as described in detail below. The safety footwear includes an upper 4 with an air permeable insole 5 having a top insole surface for supporting a foot of the wearer.

[0025]As seen in FIGS. 1, 2-3, the midsole 1 has a top midsole surface engaging the bottom insole surface 5 of the upper 4. In the longitudinal sectional view of FIG. 2 and transverse sectional views of FIGS. 6, 7 and 8 it can be seen that the midsole 1 has four transverse ventilation channels 6 that extend between outlet ports 7 in a side midsole surface and inlet ports 8 in the top midsole surface 9.

[0026]Therefore each of the four longitudinally spaced apa...

Abstract

An air exhaust outsole, for safety footwear having an upper with an air permeable insole having a top insole surface for supporting a foot of the wearer, the air exhaust outsole comprising: a midsole, with a top midsole surface engaging a bottom insole surface of the upper, the midsole including at least one ventilation channel between a side midsole surface and the top midsole surface; a puncture resistant layer with a top surface bonded to a bottom midsole surface, the puncture resistant layer comprising a puncture resistant core bonded about at least a peripheral edge in a flexible coating; and a tread layer with: a top surface bonded to a bottom surface of the puncture resistant layer; and a bottom tread surface.

Description

TECHNICAL FIELD[0001]The invention relates to an air exhaust outsole for safety footwear haying a cushioning midsole with air ventilating channels to vent the interior of the upper, and a puncture resistant layer beneath the midsole, to provide a puncture resistant footwear with a ventilated upper.BACKGROUND OF THE ART[0002]The safe use of footwear in many working environments requires foot protection to avoid common injuries. Protection may include: puncture protection from sharp objects that puncture the sole of the footwear; impact and compression resistance for the toe area; metatarsal protection that reduces the chance of injury to the metatarsal bones at the top of the foot; electrically non-conductive properties which reduce hazards that may result from static electricity buildup, or reduce the possibility of ignition of explosives and volatile chemicals; and reduce the electric hazard risk of stepping on a live electrical wire.[0003]In warehouse operations, manufacturing, he...
