  • both sides of the reinforcing member 3300 are supported by means of the first midsole 3100 , and the center thereof is not supported. That is, the first protrusions 3110 are formed on the left and right sides of the first midsole 3100 , and the second shock-absorbing spaces 3220 are provided over the first protrusions 3110 in such a manner as to be laid up and down on each other.
  • the second protrusions 3210 are provided between the second shock-absorbing spaces 3220 , and in this case, the second protrusions 3210 have a separate space formed thereinto so as to help the weight of the shoe sole light.
  • the first shock-absorbing spaces 3120 are provided under the second protrusions 3210 in such a manner as to be laid up and down on each other.
  • the reinforcing side walls 3320 serve to block the second shock-absorbing spaces 3220 from the outside and to prevent foreign matters from entering the second shock-absorbing spaces 3220 . Furthermore, the reinforcing side walls 3320 are located between the first midsole 3100 and the second midsole 3200 to permit the rear portion of the second midsole 3200 to be accommodated in a shape of U-like section, thereby suppressing the twisting of the shoe sole occurring during walking and running and thus ensuring the walking and running in a more stable manner.
  • reinforcing side walls 3320 may be extended to the lower portion of the side surfaces of the upper part of the shoe so as to partially support the lower portion of the upper part of the shoe, thereby helping the wearer walk and run stably.
