• the support part includes a support surface, the support surface being provided forward of the shock-absorbing part and having a shape extending from one end to an other end of the footwear in a width direction,
• the shock-absorbing part includes a recessed surface located at a height position lower than the support surface, and a plurality of solid columnar bodies each having a shape extending from the recessed surface to a height position identical in height to the support surface,
• a dimension between each pair of the plurality of columnar bodies directly adjacent to each other without any other of the plurality of columnar bodies between them is larger than or equal to a height dimension of each of the columnar bodies,
• the surface of each of the columnar bodies is formed in a polygonal shape as viewed from above, and
• a dimension between each pair of the columnar bodies adjacent to each other among the plurality of columnar bodies is smaller than a length of each side of the surface of each of the columnar bodies.
