A sole includes a closed cell resin foam of a low-density polyethylene (A), ethylene-vinyl acetate copolymer (B), filler (C), foaming agent (D), and cross-linker (E), wherein a mass ratio of the low-density polyethylene (A) and the ethylene-vinyl acetate copolymer (B) equals (A)/(B) within a range 90/10 to 95/5. The resin foam, molded into a predetermined middle padding member, is deformable by an external force. An elastic covering member covers the middle padding member and is configured to follow the deformation of the middle padding member abutting the covering member configured to be abutted against a foot. Weight applied to the sole crushes, and deforms a plurality of bubbles formed in the resin foam along the shape of the sole.
