Abstract
An impact absorbing material for a footwear article includes a first sheet having a plurality of projections for dispersing the force of an impact and a second sheet, having a lower durometer than the first sheet, that is bonded to the first sheet for absorbing the force from the projections. The projections are arranged on the first sheet such that nonlinear gaps are formed between adjacent pairs of projections. The impact absorbing material may be positioned between an upper and an inner liner of the footwear article and may be selectively positioned on the footwear article to protect an area on the wearer that is vulnerable to impact, such as the wearer's feet, ankles, heels or calves.
