Embodiment Construction

[0007] Referring now to the drawings, a footwear outsole 10 has a generally planer outwardly facing contact surface 12 and a sidewall 14 that extends around the periphery of the contact surface and is substantially normal to the contact surface. Extending through the outsole are a plurality of conduits 16 having opposed ends which open out of the sidewall. In the embodiment illustrated the conduits are egg-shaped in cross-section, but they could have almost any shape. In the embodiment illustrated the conduits are arrayed in parallel, spaced-apart rows and extend completely across the outsole normal to its longitudinal axis. In a preferred embodiment the conduits are equally spaced and are separated from one another by a distance c. They have a maximum width w along the longitudinal axis of the outsole.

[0008] The conduits 16 open out of the contact surface 12 of the outsole 10 through slots 18 which are formed in the contact surface. The slots 18 have a width s which is less than t...

Abstract

A footwear outsole has a generally planar outwardly facing contact surface which has a plurality of spaced-apart conduits passing through it. The conduits have opposed ends which open through the sidewall of the outsole. The conduits open to the contact surface of the outsole through slots which have a width at their intersection with the contact surface which is less than the maximum width of the conduits.

Description

BACKGROUND OF THE INVENTION [0001] Tread patterns of footwear are designed to provide optimal performance based on the intended use of the footwear. In many cases optimum performance is maximum traction. A boot that will be used for walking in mud, for example, would have a very aggressive tread with multiple protrusions with large open areas between them. Maximum traction on a smooth surface, such as concrete, is achieved by having a simple flat tread made from a sticky material such as rubber or a rubber compound. However, if the same surface has liquid on it, as might be the case with a restaurant kitchen, the liquid prevents a flat outsole from actually contacting the floor surface and it would provide little traction. To overcome this problem slots are formed in the outsole to allow the water to be squeezed out from under the outsole as it is urged against the floor. However, if these slots are wide enough to displace all of the liquid under the outsole, a large portion of the ...
