Abstract
An article of footwear has an upper, an outsole and a midsole. The outsole has upper and lower surfaces. The midsole has a midsole lower surface that contacts the upper surface of the outsole. The midsole has at least one cavity located in a heel or a forefoot portion, which cavity opens to a midsole upper surface. A cushion is located in the cavity. The cushion includes resilient balls located in a resilient matrix material. The balls have a first durometer and the matrix material has a second durometer that is different than the first durometer. The midsole has a lower cavity in the lower surface of the midsole, which lower cavity is aligned with an opening in the outsole. Balls are located in the lower cavity. A retainer keeps the balls in the lower cavity and provides a visual indication of the balls in the lower cavity.
