  • Footwear with outsole wear indicator
    Patent number: 6922916
    Abstract: The invention is a wear indicator for a footwear outsole. The wear indicator includes a plurality of strata that each have different properties, such as color. As portions of an individual stratum are worn away, corresponding portions of an underlying stratum are revealed. The underlying strata may be worn away in a similar manner to reveal further strata, thereby providing a wearer with the ability to determine the amount of wear that has occurred in an outsole.
