Abstract
An article of footwear may include an elastic membrane suspended within an interior of an upper of the article of footwear and spaced above the sole, such that a wearer's foot contacts the membrane and is cradled by the membrane as the membrane is stretched toward an underlying midsole. In some examples, the 5 membrane may contact the midsole for a discrete length of a contact area, e.g., selected by the manufacturer. In some examples, a void between the membrane and the sole is filled, at least in part, with a selected filler material. In some examples, the membrane comprises a material having tailored stretch characteristics.
