Abstract
A sole structure for a shoe includes an upper wall portion disposed on the upper side, a lower wall portion disposed below and away from the upper wall portion, and a sidewall portion that is disposed between the upper wall portion and the lower wall portion and that is elastically deformable in the vertical direction. The upper and lower wall portions and the sidewall portion are formed of resin-made wall-shaped members. A three-dimensional elastic fiber structure formed of resin fibers is provided in the interior region between the upper wall portion and the lower wall portion. The interior region includes a hollow portion that is in contact with the three-dimensional elastic fiber structure via a partition wall formed of a resin-made wall-shaped member.
