 an upper which surrounds the whole or one part of a foot of a user;   a sole which is coupled to a lower portion of the upper; and   a liner which is disposed on the sole, wherein the liner includes:
 a bottom part which is disposed on the sole; 
 one or more pairs of side surface supporting parts which are extended from a side edge of the bottom part, and partially surround a side surface of the foot of the user; and 
 one or more pairs of tightening parts which are formed at end portions of the one or more pairs of side surface supporting parts, respectively, and which tighten the bottom part and the side surface supporting part to be in close contact with the foot of the user. 
   
     
     
         2 . The shoe of  claim 1 , wherein the one or more pairs of side surface supporting parts are disposed inside the upper, and the one or more pairs of tightening parts protrude to the outside of the upper. 
     
     
         3 . The shoe of  claim 2 , wherein the upper has an opening portion through which the tightening part protrudes. 
     
     
         4 . The shoe of  claim 2 , wherein the one or more pairs of side surface supporting parts surround one or more side surfaces of a front portion, a middle portion, and a rear portion of the foot of the user. 
     
     
         5 . The shoe of  claim 2 , wherein the one or more pairs of tightening parts tighten to a top of the foot of the user. 
     
     
         6 . The shoe of  claim 2 , wherein the one or more pairs of tightening parts tighten to an ankle of the user. 
     
     
         7 . The shoe of  claim 1 , wherein the liner is made using one or more materials of synthetic resin, natural rubber, leather, and fabric. 
     
     
         8 . The shoe of  claim 1 , wherein the one or more pairs of tightening parts include tightening main bodies which protrude to the outside of the upper, respectively, coupling holes which are formed in the tightening main bodies, and a shoe strap which is fitted into the coupling hole. 
     
     
         9 . The shoe of  claim 1 , wherein the one or more pairs of tightening parts include tightening main bodies which protrude to the outside of the upper, respectively, and coupling portions which are formed on one surface of the tightening main bodies. 
     
     
         10 . The shoe of  claim 1 , wherein any one tightening part of the one or more pairs of tightening parts includes a first tightening main body, and a fitting ring formed at an end portion of the first tightening main body, and the other tightening part of the one or more pairs of tightening parts includes a second tightening main body which has a length relatively longer than a length of the first tightening main body, the second tightening main body fitted into the fitting ring. 
     
     
         11 . The shoe of  claim 2 , wherein the one or more pairs of tightening parts include tightening main bodies which protrude to the outside of the upper, respectively, coupling holes which are formed in the tightening main bodies, and a shoe strap which is fitted into the coupling hole. 
     
     
         12 . The shoe of  claim 5 , wherein the one or more pairs of tightening parts include tightening main bodies which protrude to the outside of the upper, respectively, coupling holes which are formed in the tightening main bodies, and a shoe strap which is fitted into the coupling hole. 
     
     
         13 . The shoe of  claim 2 , wherein the one or more pairs of tightening parts include tightening main bodies which protrude to the outside of the upper, respectively, and coupling portions which are formed on one surface of the tightening main bodies. 
     
     
         14 . The shoe of  claim 5 , wherein the one or more pairs of tightening parts include tightening main bodies which protrude to the outside of the upper, respectively, and coupling portions which are formed on one surface of the tightening main bodies. 
     
     
         15 . The shoe of  claim 2 , wherein any one tightening part of the one or more pairs of tightening parts includes a first tightening main body, and a fitting ring formed at an end portion of the first tightening main body, and the other tightening part of the one or more pairs of tightening parts includes a second tightening main body which has a length relatively longer than a length of the first tightening main body, the second tightening main body fitted into the fitting ring. 
     
     
         16 . The shoe of  claim 5 , wherein any one tightening part of the one or more pairs of tightening parts includes a first tightening main body, and a fitting ring formed at an end portion of the first tightening main body, and the other tightening part of the one or more pairs of tightening parts includes a second tightening main body which has a length relatively longer than a length of the first tightening main body, the second tightening main body fitted into the fitting ring.
