Appl. No.:

11/309453

Inventors:

Donald Bright - Cleveland TN, US

International Classification:

A43B 13/14

US Classification:

03602500R, 03603400R

Abstract:

A sole () for footwear has a plurality of x-shaped pillars (), preferably made of rubber or other elastomer. The x-shaped pillars () are vertical columns in the cross-sectional shape of an “X” having a wider base towards the inside of the footwear and extending, preferable in steps, to a narrower cross-section at the walking surface. The x-shaped pillars are preferably aligned longitudinally on the sole so that the arms of the x-shaped pillar face forward, rearward and to both sides of the footwear. This longitudinal orientation is preferred because it promotes gripping the engaged surface along the vertices of the x-shaped pillar, providing enhanced traction in the longitudinal and lateral directions. One embodiment has a plurality of channels () or cut throughs on a frame surrounding the x-shaped pillars and extending from the base of the x-shaped pillars through the frame to permit ejection of matter engaged between the x-shaped pillars. The sloped x-shaped pillars () compress with the weight of a person walking and inherently eject entrained matter filling the space between the arms of x-shaped pillars.

Flex-Trax, Inc. - Cleveland TN

International Classification:

B60C 1100

US Classification:

152221

Abstract:

A traction device includes a polygonal member having a number of attachment regions and a chamber with a predetermined number of sides. The chamber is disposed within a central region of the polygonal member. The number of attachment regions of the traction device is substantially equal to the predetermined number of the sides. Each chamber of the traction device is capable of dispersing at least one of fluids, solids, and fluid-solid mixtures.
