Shoe for professional truckers

1. A shoe comprising:

an upper assembly of components and a lower assembly of components cooperating to provide an interior for a person's foot and a foot opening through which a person's foot can be inserted from an exterior into the interior and removed from the interior to the exterior;

the lower assembly of components comprising an outer sole, a mid-sole overlying the outer sole on the interior, and an inner sole overlying the mid-sole on the interior, the inner sole comprising parallel slots extending through the inner sole;

the upper assembly of components comprising a hard toe cover for covering toes of a person's foot, the hard toe cover comprising a through-opening to the interior for venting the interior to the exterior and a vent cover operable from the exterior for selectively covering and uncovering the through-opening;

the outer sole comprising a bottom surface having a first zone comprising a rear tread for underlying the heel of a person's foot, a second zone comprising a front tread for underlying the ball of a person's foot, and a bridge that causes a portion of the bottom surface underlying the arch of a person's foot to be spaced from a flat horizontal surface when the shoe is resting with the two treads on that surface,

and an air exhaust system disposed in a formation in the mid-sole and comprising a first bladder pump disposed between a first group of the parallel slots and the first zone and a second bladder pump disposed between a second group of the parallel slots and the second zone, the first bladder pump having an air inlet open to the interior beneath the first group of the parallel slots, the second bladder pump having an air inlet open to the interior beneath the second group of the parallel slots, a first exhaust conduit from the first bladder pump to the exterior, and a second exhaust conduit from the second bladder pump to the exterior, and

wherein when downward pressure is applied to the inner sole by the ball of a person's foot, the air inlet of the second bladder pump is effectively sealed off to compress a charge of air that has entered through the second group of the parallel slots and force at least some of that charge through the second exhaust conduit to the exterior, and when downward pressure is applied to the inner sole by the heel of a person's foot, the air inlet of the first bladder pump is effectively sealed off to compress a charge of air that has entered through the first group of the parallel slots and force at least some of that charge through the first exhaust conduit to the exterior.

2. The shoe as set forth in claim 1 wherein the hard toe cover comprises a top wall containing the through-opening, and the vent cover is arranged for reciprocal fore-and-aft sliding on the top wall for selectively covering and uncovering the through-opening.

3. The shoe as set forth in claim 2 including a breathable fabric layer covering the through-opening in underlying relation to the vent cover.

4. The shoe as set forth in claim 1 wherein a portion of the upper assembly of components partially encircles the foot opening and comprises a breathable fabric layer band also partially encircling the foot opening for venting the interior to the exterior.

5. The shoe as set forth in claim 4 wherein the outer sole comprises a toe end, a heel end, and sides extending between the toe end and the heel end, and the upper assembly of components comprises at least one leather piece constructed and arranged to have a lower margin joining a margin of the outer sole that extends from the hard toe cover along one of the sides of the outer sole toward the heel end of the outer sole, around the heel end of the outer sole, and back to the hard toe cover along the other side of the outer sole, the at least one leather piece being further constructed and arranged to cover sides and heel of a person's foot below the breathable fabric layer band and to also cover the instep of a person's foot.

6. The shoe as set forth in claim 5 further including a tongue extending from the portion of the at least one leather piece covering the instep of a person's foot and cooperating with the portion of the upper assembly of components partially encircling the foot opening for completing encirclement of a person's foot around the ankle.

7. The shoe as set forth in claim 6 further including a strap having one end joined to the portion of the upper assembly of components that partially encircles the foot opening, the one end of the strap being disposed to one side of the tongue, and the strap having a length sufficient to extend across the tongue to an opposite end for separably attaching the latter end to the portion of the upper assembly that partially encircles the foot opening on the opposite side of the tongue.

8. The shoe as set forth in claim 7 wherein the opposite end of the strap comprises a hook-type catch and the portion of the upper assembly of components to which the opposite end of the strap separably attaches comprises a series of complementary hook-type catches, with any one of which the catch on the strap can hook to make the attachment.

9. The shoe as set forth in claim 7 wherein the hook-type catch on the strap is magnetized and the series of complementary hook-type catches are ferromagnetic.
