  • the front foot portion 1F is provided with the belt-like portion 2 and the second cleat C2, so that it may be possible to expect an improvement in stability and buffering performance in the forefoot portion 1F. Absent.
  • various shapes can be adopted as the cross-sectional shapes of the belt-like portion 2 and the groove G.
  • the depth, surface area, and the like of the groove G can be appropriately set as long as the deformation is not hindered when a bending moment is applied in the transverse direction of the belt-like portion 2.
  • one or a plurality of grooves G can be provided in one belt-like portion 2 within a range that does not hinder deformation when a bending moment is applied in the transverse direction of the belt-like portion 2.
  • the recessed portion of the belt-like portion 2 may be formed on the top surface instead of the bottom surface of the outsole 1.
  • channel G of FIG. 6C, FIG. 6D, FIG. 8B, and FIG. 8C may be provided in the upper surface instead of the said bottom face.
  • the groove G may be filled with a material having a smaller hardness (softer) than the hardness of the soft resin portion 32 forming the belt-like portion 2.
  • a midsole may be provided on the outsole 1. Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.
  • the present invention can be used for an outsole of shoes for field competitions such as soccer, rugby and American football.
