SHOE SOLE

PROBLEM TO BE SOLVED: To solve a problem that a shoe formed by sticking a felt sole with spikes inserted therein to the sole part of a shoe body side with adhesive impairs the flexibility of the felt sole, the strain of the felt sole is repeated in walking and the retention of the spikes is loosened to cause backlash and make a wearer uncomfortable in the walking. SOLUTION: This shoe sole 3 is formed with the felt sole 3a with the spikes 4 inserted therein, a rubber elastic layer 3b welded on its upper face, and a base part 3d attached to the upper face of the rubber elastic layer 3b. The rubber elastic layer 3b permeates the upper face side of the felt sole 3a to form a recessed/projecting weld part 3c intruding into fibers of the upper face side of the felt sole 3a, prevents the pull-out of engagement portions 4b of the spikes 4 and retains them on the upper face of the felt sole 3a.
