An article of footwear includes an upper, an outsole, and a midsole disposed between the upper and the outsole. The outsole is attached to the upper and has a ground-engaging surface. The midsole has a series of walls that define a series of channels extending substantially perpendicular to a longitudinal axis of the midsole and along an entire length of the midsole. The series of channels are isolated from one another and each channel receives a quantity of particulate matter therein.

A foot guard that provides shock absorption on a metatarsal region of a shoe, such as a cleat, or a foot is disclosed.

An article of footwear includes an upper, an outsole attached to the upper, and a midsole. The outsole is attached to the upper and includes a ground-engaging surface and an inner surface disposed on an opposite side of the outsole than the ground-engaging surface. The midsole includes a footbed and a bottom surface disposed on an opposite side of the midsole than the footbed and opposing the inner surface of the outsole to define a cavity therebetween. The article of footwear also includes a casing received within the casing and defining an interior void. The interior void contains a first quantity of particulate matter movable relative to the casing and a second quantity of particulate matter attached to the casing.
