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...
