Abstract
A support structure for footwear includes a longitudinally extending member to which a plurality of laterally extending supports members are secured at spaced apart locations along a length of the longitudinal member. The support structure may extend along the entire length of a footwear or may be specifically designed for the forefoot, midfoot, or hindfoot areas of a footwear. The support structure may be combined with plate-like structures or may include a plurality of longitudinally extending members. The lateral supports may extend in a generally horizontal plane or may extend in an upward or downward direction out of the horizontal plane. Furthermore, the longitudinal and lateral members may be made of different materials, or each may be made of a plurality of different materials to provide the desired characteristics of the support structure at a given location in the footwear. Different portions of the longitudinal member may be more or less flexible than the lateral supports.
