A footwear cushioning system comprising an insert (10), preferably for inclusion at the heel portion of the footwear, the insert (10) comprising a single layer of resilient, flexible web material (14), on one side of which is located a first array of projections (12) formed integrally with and extending from the web (14), and on the other side a second array of projections (16) formed integrally with and extending from the web (14), the projections (12) in the first array being located on the opposite side of the web from spaces between the projections (16) in the second array, so that when the insert (10) is compressed due to the activity of the wearer of the footwear, the projections in the first array (12) are moved relatively toward the spaces amid the projections (16) in the second array as the web resiliently flexes, providing shock absorbing cushioning to the wearer. |
