 the clasp is fixed to the upper, around a boundary part between the upper and the sole.   
     
     
         4 . The shoe according to  claim 2 , wherein
 the tightening part includes a first portion and a second portion formed continuously with each other,   the clasp is provided on both the first portion and the second portion, and,   by changing the positional relationship between the boundary of the first portion and the second portion and the clasp, the tightening force in one of the first portion and the second portion can be strengthened, and the tightening force in the other of the first portion and the second portion can be weakened.   
     
     
         5 . The shoe according to  claim 4 , wherein
 the tightening part is a shoelace,   the upper includes an eyelet part through which the first portion or the second portion passes,   an end of the first portion and an end of the second portion are fixed to a lateral side of the upper, and   the clasp is fixed to the lateral side.   
     
     
         6 . The shoe according to  claim 5 , wherein
 the eyelet part includes an outer eyelet part provided on the lateral side and an inner eyelet part provided on a medial side, and the number of the inner eyelet part is larger than the number of the outer eyelet part.   
     
     
         7 . The shoe according to  claim 5 , wherein
 the lengths of the first portion and the second portion are adjustable at at least one of the clasp, the end of the first portion, and the end of the second portion.   
     
     
         8 . The shoe according to  claim 5 , wherein
 the rearmost part of the first portion constitutes a top line of the tightening part, and the forefront part of the first portion constitutes a bottom line of the tightening part, and,   in each of the top line and the bottom line of the tightening part, the lateral side is positioned rearward of the medial side.   
     
     
         9 . The shoe according to  claim 2 , further comprising:
 a position adjustment mechanism with which the fixed position of the clasp can be shifted in a longitudinal direction.   
     
     
         10 . The shoe according to  claim 1 , wherein
 a top line on the medial side of a wearing opening in the upper is positioned forward of a top line on the lateral side of the wearing opening.   
     
     
         11 . The shoe according to  claim 1 , wherein
 the tightening part tightens the upper in a direction substantially parallel with a straight line connecting a hypothenar eminence and a thenar eminence.   
     
     
         12 . The shoe according to  claim 1 , wherein
 the tightening part includes a shoelace, and   the force transmitter includes a clasp that detachably fixes the shoelace to the upper, and a member that draws a middle part of the shoelace toward the lower part of the midfoot portion of the upper.
