The sole of the first boot or shoe includes a first metatarsal region including rounded ridges disposed adjacent to one another and extending substantially along a length of the sole and the sole of the second boot or shoe includes a second metatarsal region having rounded ridges disposed adjacent to one another and extending substantially across a width of the sole.

## Claims

### Claim 1

A footwear system for use in driving a vehicle, comprising:
a first boot or shoe and a second boot or shoe, each including a sole and an upper, said sole and upper together defining a volume for receiving a foot of a wearer,

a toe region at a distal end of the sole; and
a heel region at a proximal end of the sole with a first plurality of rounded ridges disposed adjacent to one another and extending substantially across a width of the sole;
the sole of said first boot or shoe comprising a first metatarsal region disposed substantially between toe and heel regions and along an inner side of the sole, said first metatarsal region comprising a second plurality of rounded ridges disposed adjacent to one another and extending substantially along a length of the sole; and
the sole of said second boot or shoe comprising a second metatarsal region disposed substantially between toe and heel regions and along an inner side of the sole, said second metatarsal region including a third plurality of rounded ridges disposed adjacent to one another and extending substantially across a width of the sole.

### Claim 2 (depends on 1)

The footwear system of claim 1 wherein said first metatarsal region includes a first plurality of wedge cutouts, each extending substantially in a direction transverse to a length of said second plurality of rounded ridges.

### Claim 3 (depends on 1)

The footwear system of claim 1 wherein said second metatarsal region defines a second plurality of wedge cutouts, each said cutout extending substantially in a direction transverse to a length of said third plurality of rounded ridges.

### Claim 4 (depends on 3)
