 a midsole member; and   a side reinforcement member configured to support a lateral side of the midsole member against the ground,   wherein the side reinforcement member has a resilient curved portion formed integrally therewith to resiliently support the lateral side of the midsole member.   
     
     
         2 . The article of footwear according to  claim 1 , wherein the resilient curved portion is formed by partially bending a portion of the side reinforcement member. 
     
     
         3 . The article of footwear according to  claim 1 , wherein the resilient curved portion includes concave portions and convex portions arranged in a zigzag pattern. 
     
     
         4 . The article of footwear according to  claim 1 , wherein the side reinforcement member includes:
 an upper reinforcement portion having an upper end secured to the midsole member and a lower end becoming a free end; and   a lower reinforcement portion having a lower end secured to the midsole member and an upper end becoming a free end,   wherein the resilient curved portion integrally connects the lower end of the upper reinforcement portion and the upper end of the lower reinforcement portion.   
     
     
         5 . The article of footwear according to  claim 1 , wherein the midsole member has a side recess formed at the lateral side thereof, and
 the side reinforcement member covers the side recess while being disposed apart from the side recess.   
     
     
         6 . The article of footwear according to  claim 5 , wherein the side reinforcement member is continuously formed along the lateral side of the midsole member, and
 the lateral side of the midsole member and the side reinforcement member create a sealed shock-absorbing space therebetween.   
     
     
         7 . The article of footwear according to  claim 5 , wherein the side reinforcement member is provided in plural, the side reinforcement members being spaced apart from each other along the lateral side of the midsole member, and
 the lateral side of the midsole member and each of the side reinforcement members create an opened shock-absorbing space therebetween.   
     
     
         8 . The article of footwear according to  claim 5 , wherein the midsole member has a through-hole formed therethrough in a transverse direction so as to communicate with the side recess. 
     
     
         9 . The article of footwear according to  claim 1 , wherein the midsole member has a dent formed on at least one of a top surface and a bottom surface thereof. 
     
     
         10 . The article of footwear according to  claim 1 , further comprising:
 a reinforcement core made of a material having higher resilience than the midsole member and accommodated in the midsole member.   
     
     
         11 . The article of footwear according to  claim 1 , wherein the side reinforcement member is made of a light-transmitting material. 
     
     
         12 . The article of footwear according to  claim 1 , further comprising:
 an outsole member provided beneath the midsole member,   wherein the side reinforcement member supports the midsole member to be spaced apart from the outsole member.   
     
     
         13 . The article of footwear according to  claim 12 , wherein the side reinforcement member further includes a bottom portion, and
 the bottom portion has an outer surface secured to a top surface of the outsole member.
