s3, sequentially placing the soleplate (1) with the shoe spike, the middle sole layer (2) and the upper layer (3) which are pressed in the step S1 on a shoe mold, simultaneously placing the high-elasticity ring (5) obtained in the step S2 in a cavity formed by the groove (21) and the clamping groove, sequentially coating a layer of glue on a contact surface, then performing press molding through the mold, cooling and demolding to obtain the sole of the high-elasticity running shoe;
s4, placing the sole manufactured in the step S3 at the lower end of a shoe tree, and sewing the shoe fabric and the sole along the circumferential direction of the shoe tree to obtain a semi-finished running shoe;
s5, polishing and painting the semi-finished running shoes obtained in the step S4 to obtain high-elasticity running shoe finished products;
and in the step S3, the mold temperature is kept at 55-65 ℃ in the sole pressing process, the mold is opened after pressing molding is carried out for 10-15min, and then the mold is taken out.
