Claim:
1. A shock absorbing shoe with improved assembly and operational performance, comprising: an outsole ( 10 ); an upper sole ( 20 ) having a guide portion ( 21 ); and a pair of support units disposed between the outsole ( 10 ) and the upper sole ( 20 ), wherein each of the support units includes: a first support body ( 30 A) bonded to the outsole ( 10 ); and a second support body ( 30 B) bonded to the upper sole ( 20 ) and having a first guide part ( 33 ) at a position corresponding to the guide portion ( 21 ); a first holding body ( 35 ) bonded to the first support body ( 30 A), wherein the first holding body ( 35 ) includes a first annular rim ( 35 d ) formed along an edge thereof, a first seat depression ( 35 e ) formed by the first annular rim ( 35 d ), a first fitting protrusion ( 35 c ) formed at a center of the first seat depression ( 35 e ), and a through-hole ( 35 b ) formed at a center of the first fitting protrusion ( 35 c ); a second holding body ( 37 ) bonded to the second support body ( 30 B), wherein the second holding body ( 37 ) includes a second annular rim ( 37 d ) formed along an edge thereof, a second seat depression ( 37 e ) formed by the second annular rim ( 37 d ), a second fitting protrusion ( 37 c ) formed at a center of the second seat depression ( 37 e ), a protruding spacer part ( 36 ) protruding from the second fitting protrusion ( 37 c ) toward the first fitting protrusion ( 35 c ), and a second guide part ( 37 a ) formed at a center of both the second fitting protrusion ( 37 c ) and the protruding spacer part ( 36 ); a single coil spring ( 41 ) disposed between the first holding body ( 35 ) and the second holding body ( 37 ), wherein one end of the single coil spring ( 41 ) is fitted into the first seat depression ( 35 e ), and the other end of the single coil spring ( 41 ) is fitted into the second seat depression ( 37 e ); and a flexible supporting member ( 50 ) passing through the first guide part ( 33 ), the second guide part ( 37 a ), the single coil spring ( 41 ) and the through-hole ( 35 b ), wherein a protruding spacer part ( 36 ) has a length configured in such a way that, when the protruding spacer part ( 36 ) contacts the first fitting protrusion ( 35 c ) during compression, full compression of the single coil spring ( 41 ) is inhibited, and a space remains between the first annular rim ( 35 d ) and the second annular rim ( 37 d ) to thereby prevent the single coil spring ( 41 ) from being damaged due to over-compression and allow bending of the flexible support member ( 50 ).
